 The rise of libraries and web development frameworks, such as Angular, React, Node, jQuery, etc., have pushed the boundaries of JS programming. We now have entire technology stacks written in JavaScript; it is the first language to be used thus.

Server-side scripting with JavaScript was a major resurgence for the language in the face of stiff competition from Java and Python.

Now, you can use just one language to make client HTTP requests, generate dynamic content in web browsers, build robust microservices, design UIs, and much more.

 The immense potentiality of the language, coupled with an exponential increase in the computing power of user devices, has led to the rise of client-side rendering, amazingly capable frameworks, and edge computing.

Front-end, back-end, mobile, desktop, cloud, ML & DL — JS has become ubiquitous. Millions of web pages use JavaScript to make everything interactive, robust, and feature-rich.

What are Some of the Most Crucial Factors of JavaScript Programming one should be aware of?

Some of the most important aspects of JavaScript programming that every web development expert and aspiring developer must master are:

Defines the parameters of access pertaining to a variable or function;

Destructuring

The process of unpacking values from arrays, collections, and objects;

JavaScript DOM HTML

An acronym for the core Document Object Model API, the data representation of all the elements in a website’s HTML code. JavaScript used DOM to access and manipulate elements in the HTML code.

JQuery is a feature-rich, fast, cross-platform, and lightweight JavaScript library that enables quick & easy DOM manipulation, HTML traversal, and event handling. It is a really handy tool for creating interactive and engaging client-side interfaces.

Cookies and Events

Events are how JS interacts with HTML and provides dynamism to a page. JS uses cookies to speed up event handling, client-side rendering, page load times, etc.

Functions lie at the heart of any operation that JS does. If you wish to crack every JavaScript assignment and homework, you must be a pro at designing your own and working with functions.

Call Stack: JS needs to track each function call closely as an OOP and functional programming/scripting language. It uses a special data structure called the call stack to remember all the functions called in a process.

The Fetch API

The fetch API or packaged method is an asynchronous method used to fetch resources from a server.

IIFE or Immediately Invoked Function Expressions are special functions that are central aspects in nearly every JS programming language. These functions speed up priority operations as they are immediately executed after creation.

Still, if you are getting stuck on this topic and asking someone to ‘ do my coding homework ‘ then you can always hire the best tutors to understand the programming concepts.

Here’s a Simple Example of a JavaScript Program

This is just an example of JavaScript code written by our experts. Our code is written in such as way that it is easily understandable by students.

What is JavaScript?

JavaScript is a CS (Client Side) scripting language. It is in no way related to Java as it's name suggests, but it is used for client side scripting. By Client Side scripting, i mean the ability to manipulate data, the DOM and a webpage as a whole, without having a backend service or language. Using JavaScript application development, you can build cross-platform HTML 5+ JavaScript applications and developers can embed functionality created by the third party into their applications, such as Facebook API and Twitter API. JavaScript is also used for a scripting language to develop robust and powerful network applications, mostly server-side ones.

Validations can be done dynamically on the static HTML page by using JavaScript JavaScript validates based on specific patterns like The phone number should consist of 10 numbers with 7,8,9 in 1st position. JavaScript is so easy to get started but overwhelming. Because today, more of us are writing JavaScript than ever before, and if you've been coding for long, you may recognise the value of testing, linting, bundling, transpiling, automated builds, and more, but all too often, we ignore many of these items.   Why? Because setting up a solid JavaScript development environment is so much work. The list of choices is so long and complex that it's hard to know even where to get started. and we are  here to help. A great JavaScript development environment makes doing the right thing the easy thing.  we'll make it happen.

Java and JavaScript are two different programming language which  have different syntax, semantics, and uses. so, Do not confuse JavaScript with the Java programming language. Java is an object oriented and general-purpose programming language. It's platform independent code. compiled one run on multiple platforms, including desktop, mobile and the web. JavaScript (JS) is most well-known scripting language used  for design  Web pages. It is a lightweight, interpreted, or just-in-time compiled programming language with first-class functions.

JavaScript Promises: Who needs the complication of writing code to handle asynchronous activities that happen out of your app's control, such as network requests and file I/O? JavaScript Promises make asynchronous code as easy to write as doThis().then(that).then(something_else).

There are many important topics to learn when it comes to JavaScript, but some key areas that are essential for mastering the language include:

Fundamentals of JavaScript: This includes understanding the syntax, data types, variables, operators, and control flow.

Objects and Arrays: Understanding how to work with objects and arrays in JavaScript is essential for many tasks, such as manipulating data and working with JSON.

Functions: Functions are a fundamental building block in JavaScript and are used for code reuse and modularity.

DOM manipulation: The Document Object Model (DOM) is a programming interface for HTML and XML documents, understanding how to manipulate the DOM is crucial for web development.

Asynchronous Programming: JavaScript is a single-threaded language, so understanding how to work with asynchronous code is essential for building responsive and efficient web applications.

Event handling: Understanding how to handle events in JavaScript is essential for building interactive web applications.

Libraries and Frameworks: Learning popular libraries and frameworks such as jQuery, React, Angular, and Vue can help you to build more complex applications more efficiently.

Debugging and Testing: Being able to troubleshoot and test your code is an important skill for any developer.

Best Practices and performance optimization: I t's important to keep in mind the best practices, performance optimization and security concerns while developing web applications.

ES6 and beyond: JavaScript has evolved over the years, and understanding the newest features of the language like ES6, ES7, and ES8 is important to write modern and more efficient code.

It's worth noting that JavaScript is a vast and constantly evolving language, so it's important to continue learning and staying up to date with the latest developments in the field.

JavaScript can be a tricky language to master, but with the help of CodersArts experts, you can learn the ins and outs of this powerful programming language. Our team of experienced developers and tutors are here to help you with all your JavaScript needs, from basic coding to complex projects.

JavaScripts sample assignments

Assignment title: surface area, problem statement.

Create a variable containing an object that will contain three properties that store the length of  each side of the box.

Prompt the user for 3 side lengths and  store them in the properties of the object.

Create a function named calcArea that accepts one parameter, the object we created earlier. Using the formula below,calculate and return the surface area.

Use template literals to display the three sides of the box and the final surface area with descriptive text.

Sample Output 

Side A=3, side B =4, side C=5

The surface area is:94.

In this application we create an array of objects  that is A,B and C with assign value zero. In the second step we take three Input using prompt and store value above  objects. In the next step  we create a calcArea function to calculate the area of the surface. Then show the result on the console log.

Assignment Title: Hangman Game

Problem statement .

Create a secret word that the player will have to guess and store in a JavaScript variable. The words must be in English and use the simple Latin alphabet (All uppercase, no accents).

console.log the secret word so you can peek while debugging. 

Create the clue. Make a string that contains that many underscore characters (_) for every letter in the secret word. Display it on the page in the clue section. Don't hard code this! It must compute a new one if you change your secret word.

When the player clicks on a letter, determine if the letter is in the secret message and show all of the locations of that letter in the clue.

If the letter is not in the message, a body part is added to the hangman. (Change the image. Note that the images are numbered.) The player has six wrong guesses before they lose.

Dim each letter as it is guessed. (There is a CSS class for that called used.)

Do not do anything if the player selects the same letter again and doesn't count it against them.

If the player wins, show the "You Win!" image. If the player loses, show the "You Lose!" image and display the secret word in the clue section.

When the game is over remove the event handler so they can't play anymore and show the message at the bottom to tell the player that the game is over.

This app tracks and updates the number of guesses remaining, correct and incorrect letters already guessed, and the users score for the amount of correctly guessed words. Key events listen for the letters that the user types. After the user wins/loses, another word is automatically chosen. This also resets the number of guesses remaining, letters guessed and a new game begins. In this Application we have to write  javascript code, first we create a let type variable word that holds 'HANGMAN' word, and then one other variable x that holds zero. After that we create a clue array and  then execute for loop length of word and assign '_' to the clue array. after that add an event listener  then perform if condition. and add a class used after that to perform a for loop , in this loop assign letter one by one to the clue array and set flag false. After that one if in this condition one switch loop  for display hangman images.then check win or lose. after  the condition, create isHnagmanFulld function. It has a parameter that is a clue array.

Assignment Title: Tic-Tac-Toe game using JavaScript

Create two variables called playerX and playerO. Set them to the DOM element with the id "x" and "o" respectively. This is the text at the top that says who's turn it is.

Create a named function with a meaningful name of your choosing. (This will be referred to as the "event handler" in further instructions.) In this   function add a console.log() statement to display a message in the console.

Create a variable that contains all of the TD elements. Use a for loop or the .forEach() method to add the function as a click event handler to each of the TD elements. Be sure to use.addEventListener() rather than older methods of adding event handlers.  Open the console and click a square. You should see the message from your console.log.

In your event handler, add a statement to get the id value of the element with the class "current player" and store it to a variable. Display this value using the same console.log() you already have. Try clicking a square to see the value.

 At the end of your event handler, add a statement to switch the "current-player" class from the playerX to playerO elements or visa-versa. (Remember you can toggle classes.) Try clicking a few squares, you  should see the player at the top of the page change as well as the output in the console.

In your event handler, add a statement to add the class "x" or "o" to the target element depending on who's turn it is. (the target element is the one that was clicked on. Hint: the event object has a target property.) You should see "X" or "O" appear in the square when you click on it. (The letter is displayed using CSS, refer to that file if you want to see how it is done.)

Add an event handler to the "New Game" button to clear all the squares.

Notice that if you click on a square that is taken by the other player, the marker may turn into a question mark. This is because you have added both "x" and "o" classes to the document. If you used className instead of classList you would be able to take over another player's square. Also, if you click on your own square you waste your turn. Modify the eventhandler to check to see if there is a class on the element already.(Hint: this is a good use of className but there are other ways to do it.) Don't put a marker or count the turn if the square is already taken.

Notice that there is a file called winner.js already referenced from the HTML file. This contains a function called checkWin(). Since it is included before the main.js file, you can call this function from your code. You can examine this function so that you understand how it works. Call the checkWin() function from the event handler. The first argument is a string identifying the player, "x" or "o". The second argument is the list of td elements you selected previously.

If there is a winner the checkWin() function will return an array of  the winning elements, set the background colour to yellow of the three winning squares to highlight them and open an alert box to say who the winner is. Depending on which browser you use, you may not see the last markeror the highlight color until you close the alert box. This is fine. There is a trick to fix this but don't worry about it.

In the event handler for the "New Game" button, add code to  remove the background colour.Play Tic Tac Toe!

In our program or design [Tic Tac Toe Game], at first, on the webpage, there is a selection box with the game title and two buttons which are labeled as “Player(X)” and “Player(O)”. Users must select one option or button to continue the game. If the user selects the X then the bot will be O and if the user selects the O then the bot will be X. Once the user selects one of them, the selection box will disappear and the playboard is visible. In the above  image we show the X player is  winer and below the image show the Player O is winer. At the center of the webpage, there is a tic tac toe play area with nine square boxes. Once you click on the particular box then there is visible a sign or icon which you have chosen on the selection box. Once you click on any box then after a couple of seconds the bot will automatically select the box which was not selected by you or the bot before, and the opposite icon is visible there means if your icon is X then the bot will have O.Once a match is won by someone, the playboard section will stop and the result box appears with the winner's sign  and change background color.

Assignment Title: An Online Car Rental System

The website should be dynamic which means all the data is loaded dynamically from theJSON file. If the contents in the JSON file change (e.gThe mileage changes to 12354 forid=1), the pages should change as well.

The vehicles available for renting can be divided into three categories: Sedan, Wagon andSUV.

Car image samples are provided on the CANVAS

You need to create a folder “images' 'that stores the pictures for the cars. Each image is named according to the model of the car and the image types are all “jpg”.

Assignment Specification

This assignment requires that you do the following steps:

Design a JSON file “cars.json” with the structure specified in requirement 3 and store at least 10 + car data items in the JSON file. Set up the availability state to “True” for 70%of cars in the Warehouse, and a “False” state to the other 30%

Use AJAX to load the JSON file “cars.json” and extract the data and save it as arrays in your webpage.

Display the cars in a nice tabular format using the above arrays on your webpage for users to select.

Provide a “button” to add the car to the reservation “shopping cart”. Use AJAX to check the availability of the car after clicking the button (the field “availability” is included in cars.json). If the availability is “True” then add the car to the reservation shopping cart and prompt success; If the availability is “False” then alert that “Sorry, the car is not available now. Please try other cars' '.

Provide a button/link to view the reservation shopping cart. Display the cars which have been added into the reservation shopping cart (hint: use session to store the data). Users can set the “rent days' ' or delete cars in the shopping cart.

Provide the checkout button to check if there are cars in the shopping cart. If no, then alert“No car has been reserved.” and jump to the first page. If yes, validate the “rental days” (integer, >0) using JavaScript and navigate to the next page.

Design the checkout page which displays a purchase form asking the user to fill in their delivery details (name, email address, mailing address, city, state, post-code and payment type). All these fields must be completed for the order to go ahead. Validate the format of the email address. If all details are filled correctly, then direct the user to a page showing the delivery details and the cost.

This project is designed so as to be used by Car Rental Company specializing in renting cars to customers. It is an online system through which customers can view available cars, register, view profiles, and book cars. A car rental is a vehicle that can be used temporarily for a period of time with a fee. Renting a car assists people to get around even when they do not have access to their own personal vehicle or don't own a vehicle at all. The individual who wants to rent a car must first contact the car rental company for the desired vehicle. This can be done online. At this point, this person has to supply some information such as; dates of rental, and type of car.

Aims & Objectives

To produce a web-based system that allows customers to register and reserve cars online and for the company to effectively manage their car rental business.

To ease customer’s tasks whenever they need to rent a car.

Benefits of Online Car Rental Services 

This online car rental solution is fully functional and flexible.

It is very easy to use.

This online car rental system helps in back office administration by streamlining and standardizing the procedures.

It saves a lot of time, money, and labor.

The software acts as an office that is open 24/7.

Assignment Title: Online Examination

Requirement.

The problem with the current system is that students take their exam manually. This outdated system will take long time utilization; the manual procedure used for conducting exams is a time consuming process. More time is being used for lecturers to bring the questions papers and answer sheets and also more time is needed for students in order to write their exam. Students are not satisfied with the current system of taking the multiple choice examination. The no accuracy with current system when students did not use a 2b pencil student are losing their mark. Using the manual procedure of conducting examinations we are not saving the environment by using more paper, we are in a world where we really need to take care of the environment.

This project is aimed at developing an online examination system for introduction to management for students and lecturers. The purpose of the system is to completely automate the old manual procedure of conducting exams to a computerized System. I will provide a more efficient examination system. The system will allow students to register and take the exam. This project has many categories of tests like HTML,CSS,JAVASCRIPT etc. Students can choose a category of test and click on submit button then student take test. After submitting the test, the scorecard will become a scorecard on the screen. After the display score card, students can logOut.

Ruslana Sereda

Technical editor

According to  Statista , in 2022, the number of mobile devices worldwide reached 15.96 billion, compared to 14.91 billion in 2021. It is expected that by 2025, this figure will reach 18.22 billion.

The popularity of mobile apps is growing, and apps are becoming one of the best ways to communicate with customers. With the onset of the coronavirus pandemic, this issue has become particularly relevant. Many companies were forced to rethink their business models and consider launching their own IT products for smartphones and tablets.

It's not surprising that mobile development is in high demand, and the demand is continuously increasing.

It is expected that in 2023, mobile applications will generate revenue of over $ 542 390.54  million, and by 2027, it will reach $732,753.98 million.

When it comes to developing digital products, the first step is to determine the programming language for your mobile or web application. There are numerous options, but JavaScript is the most well-known and in-demand language.

Over the last 10 years, JavaScript has consistently been among the top five popular languages among developers, according to  GitHub . Regarding usage activity, JavaScript confidently holds the  first position  year after year.

Is JavaScript used for mobile apps? Absolutely! The experts at Lampa Software have prepared material that addresses the following questions:

Can you make mobile apps with JavaScript?

What advantages does JavaScript offer for mobile apps?

Which frameworks are used for creating cross-platform mobile apps in this language?

How to create mobile apps with JavaScript to obtain a high-quality and efficient digital product?

• Understanding JavaScript in Mobile App Development

JavaScript is a programming language that revolves around scripts describing the necessary actions for processing and execution. Every mobile operating system can work with scripts, making JavaScript a cross-platform language.

The popularity of JavaScript is not a coincidence; it has several undeniable advantages:​

Since JavaScript is a versatile programming language, it's suitable for creating both native and hybrid mobile apps.

A native app is developed for specific platforms, while building hybrid mobile apps involves using a single codebase that can run on multiple operating systems.

• Exploring JavaScript Frameworks for Mobile Apps

A framework is a software environment that provides a foundation for creating apps or software. It consists of various libraries and tools and significantly helps speed up and simplify the development process.

There are many frameworks, and they all differ: some allow for native app development (for specific operating systems like iOS or Android).

Now, let's explore three highly sought-after frameworks:

React Native

This is an environment for JavaScript for mobile app development, allowing the creation of digital products with a customized interface for Android and iOS. The JS framework enables building applications for various operating systems using a single codebase.

React Native is widely used to support multiple digital solutions. Notable React Native apps include Instagram, Facebook, Skype, Uber Eats, Walmart, Wix, Bloomberg, and more.

Let's take a look at the advantages of React Native:

Ionic is a JavaScript framework for developing hybrid or cross-platform digital solutions utilizing HTML, CSS, and JavaScript.

Apps like MarketWatch, Diesel, Untappd, Sworkit, and others have been developed on Ionic.

The framework has undergone numerous changes, ultimately providing mobile developers various technologies like VU.js, Angular, and React. Its slogan, "One Codebase, any Platform," holds true.

Ionic's advantages include:

Support for other frameworks: With the option for integrations, Ionic can be combined with several different frameworks, making development even more convenient.

In-built testing environment: When working with Ionic, there's no need for emulators or external devices. The programming is done in JavaScript and HTML/CSS, which any browser can handle.

Plugin support: Integrating third-party plugins expands the framework's capabilities, adding extra features and solving more tasks with Ionic-based apps.

NativeScript

NativeScript is a development open-source JavaScript framework for developing native mobile apps, empowering developers to control their platform with JavaScript instead of Objective-C (iOS) or Java (Android).

Apps like Groovebook, JustWatch, Nstudio, Washmen, Spotless, and more have been built using NativeScript.

The key advantages of the framework are:

Community: Since its release, this app development framework has gained favor among developers, resulting in a wide community that continuously releases new plugins as successfully as the framework's creators.

Support for external frameworks: When creating an app, you're not limited to using just this framework. Support for external frameworks like Angular expands the development process's possibilities.

Support for external libraries: Despite having its JavaScript library, this cross-platform framework allows you to add other libraries, such as jQuery mobile, without extra layers.

Choosing the most suitable option for creating a mobile app with JavaScript will depend on the functionality of your IT solution and your business needs.

• Building Cross-Platform Mobile Apps with JavaScript

Cross-platform apps are digital solutions that operate on multiple operating systems.

JavaScript app development allows you to cover two operating systems, iOS and Android, with a single codebase. It does not require writing code in the native programming language but provides a nearly native experience through a visualization interface using custom controls.

This approach has several advantages:

Maximum reach to the target audience: If you know that your customers use both Android and iOS, targeting all types of mobile devices helps expand your audience.

Development cost optimization: A unified technology stack for both Android and iPhone, involving fewer specialists and a simplified development process, all contribute to saving costs while delivering a quality application.

Easy maintenance and deployment: Deployment is much faster due to a unified codebase that integrates seamlessly with any operating system. Maintenance and making changes are also easier since they only affect one codebase.

Cross-platform JavaScript mobile app development is carried out using frameworks.

These frameworks play a crucial role in enabling code sharing and reusability. To optimize code reuse while maintaining OS-specific features, you need to:

Create common abstractions and interfaces that can be reused on different platforms.

Use conditional statements and flags to determine actions based on the platform.

Divide JavaScript code into modules to easily replace and add functionality for different platforms.

Utilize plugins and libraries that provide platform-specific functionalities.

• Developing Native-Like User Interfaces

In today's world, mobile apps are essential business tools that are another channel for sales and customer engagement. Therefore, it's crucial to create a native product that performs excellently and meets business needs.

Moreover, JavaScript frameworks offer extensive capabilities for creating native user interfaces (UI) and enhancing the user experience (UX) in mobile apps.

Let's explore some of these capabilities:

Component-based approach: Frameworks like React Native and NativeScript are built on a component-based approach, allowing you to break the user interface into small, reusable components. This simplifies the development, maintenance, and expansion of the app's interface.

Access to native components: These frameworks enable the use of native components and platform APIs, enabling the creation of truly native iOS and Android apps.

Animations and transitions: The frameworks provide tools to create smooth animations and transitions between screens, enhancing the user experience and making the app more appealing.

Responsive design: JavaScript frameworks allow you to create designs that adapt to different screen sizes and device orientations, ensuring a good user experience across various smartphones.

Use asynchronous requests, virtual rendering, and component memoization to optimize performance and responsiveness in JavaScript-based mobile apps. Cache data on the mobile device and conduct regular testing.

• Accessing Native Device Features and APIs

JavaScript frameworks are created to bridge the gap between web technologies and built-in device functionalities. They enable developers to create cross-platform solutions with access to smartphone functionalities while using common code and development principles of JavaScript for mobile apps.

How is this achieved? Frameworks allow developers to access native mobile device features, such as the camera, GPS, notifications, and sensors, through specialized APIs and libraries. They abstract the differences between platforms and provide a unified interface for working with various smartphone features.

It is essential to use specialized libraries for each operating system to ensure more reliable interaction with native device capabilities, better performance, simplified support, and app maintenance.

Furthermore, plug-in modules often offer broader functionality and flexibility when configuring and integrating with other application parts.

• Testing and Debugging JavaScript Mobile Apps

These are essential stages that allow for detecting and fixing errors in the early stages of software development, ensuring quality and stable operation of the application, and enhancing the user experience.

Let's explore the most common methods and tools that can be used for this purpose.

• Unit Testing

You can use frameworks like Jest, Mocha, or Jasmine for modular testing of components and functions in a JavaScript application. They enable writing tests for each part of the code and verify that the functionality works correctly.

• Integration Testing

You can apply integration tests to test the interaction of different components in the app. Here, tools that emulate user interactions with the product are used to check that the components interact correctly. Some popular tools in this area are Cypress, Detox, and Appium.

• Browser Debugging

Many JavaScript mobile development frameworks support browser debugging. This allows using browser developer tools such as Chrome DevTools or Safari Web Inspector to track errors, analyze code, check the application's state, and set breakpoints to find issues.

• Performance Optimization and App Store Guidelines

Optimizing performance and meeting App Store requirements are critical for a successful mobile app. To optimize performance, a developer needs to:

Use lazy loading for components and resources.

Compress images and use formats like WebP.

Reduce the number of HTTP requests by combining files and using sprites for images.

Minimize and merge JavaScript files.

Use virtual rendering.

To ensure the app meets App Store requirements, you should:

Test it on different devices.

Ensure the security of user data and compliance with privacy policies.

Address all critical errors and gaps.

Additionally, if your app uses payments, comply with App Store payment system rules.

Following these recommendations will help improve your app's performance and successfully publish it on the App Store.

• Overcoming Challenges and Best Practices

During mobile product development, various challenges may arise, affecting the process and app quality.

The most common challenge is compatibility and adaptation to different devices and operating systems. Regular testing can solve this issue. Additionally, you should use platform-specific features and plugins and adapt the design and interface to different screens.

To facilitate development, support, and collaboration on the project, consider the following approaches:​

These are just a few practices that you should apply to develop high-quality and efficient digital products.

Can I make mobile apps with JavaScript? Yes. It is the most popular and in-demand programming language actively used for creating mobile digital products.

JAVASCRIPT ASSIGNMENT OPERATORS

In this tutorial, you will learn about all the different assignment operators in javascript and how to use them in javascript.

Assignment Operators

In javascript, there are 16 different assignment operators that are used to assign value to the variable. It is shorthand of other operators which is recommended to use.

The assignment operators are used to assign value based on the right operand to its left operand.

The left operand must be a variable while the right operand may be a variable, number, boolean, string, expression, object, or combination of any other.

One of the most basic assignment operators is equal = , which is used to directly assign a value.

Assignment Operators List

Here is the list of all assignment operators in JavaScript:

In the following table if variable a is not defined then assume it to be 10.

Assignment operator

The assignment operator = is the simplest value assigning operator which assigns a given value to a variable.

The assignment operators support chaining, which means you can assign a single value in multiple variables in a single line.

Addition assignment operator

The addition assignment operator += is used to add the value of the right operand to the value of the left operand and assigns the result to the left operand.

On the basis of the data type of variable, the addition assignment operator may add or concatenate the variables.

Subtraction assignment operator

The subtraction assignment operator -= subtracts the value of the right operand from the value of the left operand and assigns the result to the left operand.

If the value can not be subtracted then it results in a NaN .

Multiplication assignment operator

The multiplication assignment operator *= assigns the result to the left operand after multiplying values of the left and right operand.

Division assignment operator

The division assignment operator /= divides the value of the left operand by the value of the right operand and assigns the result to the left operand.

Remainder assignment operator

The remainder assignment operator %= assigns the remainder to the left operand after dividing the value of the left operand by the value of the right operand.

Exponentiation assignment operator

The exponential assignment operator **= assigns the result of exponentiation to the left operand after exponentiating the value of the left operand by the value of the right operand.

Left shift assignment

The left shift assignment operator <<= assigns the result of the left shift to the left operand after shifting the value of the left operand by the value of the right operand.

Right shift assignment

The right shift assignment operator >>= assigns the result of the right shift to the left operand after shifting the value of the left operand by the value of the right operand.

Unsigned right shift assignment

The unsigned right shift assignment operator >>>= assigns the result of the unsigned right shift to the left operand after shifting the value of the left operand by the value of the right operand.

Bitwise AND assignment

The bitwise AND assignment operator &= assigns the result of bitwise AND to the left operand after ANDing the value of the left operand by the value of the right operand.

Bitwise OR assignment

The bitwise OR assignment operator |= assigns the result of bitwise OR to the left operand after ORing the value of left operand by the value of the right operand.

Bitwise XOR assignment

The bitwise XOR assignment operator ^= assigns the result of bitwise XOR to the left operand after XORing the value of the left operand by the value of the right operand.

Logical AND assignment

The logical AND assignment operator &&= assigns value to left operand only when it is truthy .

Note : A truthy value is a value that is considered true when encountered in a boolean context.

Logical OR assignment

The logical OR assignment operator ||= assigns value to left operand only when it is falsy .

Note : A falsy value is a value that is considered false when encountered in a boolean context.

Destructuring assignment

The two most used data structures in JavaScript are Object and Array .

• Objects allow us to create a single entity that stores data items by key.
• Arrays allow us to gather data items into an ordered list.

However, when we pass these to a function, we may not need all of it. The function might only require certain elements or properties.

Destructuring assignment is a special syntax that allows us to “unpack” arrays or objects into a bunch of variables, as sometimes that’s more convenient.

Destructuring also works well with complex functions that have a lot of parameters, default values, and so on. Soon we’ll see that.

Array destructuring

Here’s an example of how an array is destructured into variables:

Now we can work with variables instead of array members.

It looks great when combined with split or other array-returning methods:

As you can see, the syntax is simple. There are several peculiar details though. Let’s see more examples to understand it better.

It’s called “destructuring assignment,” because it “destructurizes” by copying items into variables. However, the array itself is not modified.

It’s just a shorter way to write:

Unwanted elements of the array can also be thrown away via an extra comma:

In the code above, the second element of the array is skipped, the third one is assigned to title , and the rest of the array items are also skipped (as there are no variables for them).

…Actually, we can use it with any iterable, not only arrays:

That works, because internally a destructuring assignment works by iterating over the right value. It’s a kind of syntax sugar for calling for..of over the value to the right of = and assigning the values.

We can use any “assignables” on the left side.

For instance, an object property:

In the previous chapter, we saw the Object.entries(obj) method.

We can use it with destructuring to loop over the keys-and-values of an object:

The similar code for a Map is simpler, as it’s iterable:

There’s a well-known trick for swapping values of two variables using a destructuring assignment:

Here we create a temporary array of two variables and immediately destructure it in swapped order.

We can swap more than two variables this way.

The rest ‘…’

Usually, if the array is longer than the list at the left, the “extra” items are omitted.

For example, here only two items are taken, and the rest is just ignored:

If we’d like also to gather all that follows – we can add one more parameter that gets “the rest” using three dots "..." :

The value of rest is the array of the remaining array elements.

We can use any other variable name in place of rest , just make sure it has three dots before it and goes last in the destructuring assignment.

Default values

If the array is shorter than the list of variables on the left, there will be no errors. Absent values are considered undefined:

If we want a “default” value to replace the missing one, we can provide it using = :

Default values can be more complex expressions or even function calls. They are evaluated only if the value is not provided.

For instance, here we use the prompt function for two defaults:

Please note: the prompt will run only for the missing value ( surname ).

Object destructuring

The destructuring assignment also works with objects.

The basic syntax is:

We should have an existing object on the right side, that we want to split into variables. The left side contains an object-like “pattern” for corresponding properties. In the simplest case, that’s a list of variable names in {...} .

For instance:

Properties options.title , options.width and options.height are assigned to the corresponding variables.

The order does not matter. This works too:

The pattern on the left side may be more complex and specify the mapping between properties and variables.

If we want to assign a property to a variable with another name, for instance, make options.width go into the variable named w , then we can set the variable name using a colon:

The colon shows “what : goes where”. In the example above the property width goes to w , property height goes to h , and title is assigned to the same name.

For potentially missing properties we can set default values using "=" , like this:

Just like with arrays or function parameters, default values can be any expressions or even function calls. They will be evaluated if the value is not provided.

In the code below prompt asks for width , but not for title :

We also can combine both the colon and equality:

If we have a complex object with many properties, we can extract only what we need:

The rest pattern “…”

What if the object has more properties than we have variables? Can we take some and then assign the “rest” somewhere?

We can use the rest pattern, just like we did with arrays. It’s not supported by some older browsers (IE, use Babel to polyfill it), but works in modern ones.

It looks like this:

In the examples above variables were declared right in the assignment: let {…} = {…} . Of course, we could use existing variables too, without let . But there’s a catch.

This won’t work:

The problem is that JavaScript treats {...} in the main code flow (not inside another expression) as a code block. Such code blocks can be used to group statements, like this:

So here JavaScript assumes that we have a code block, that’s why there’s an error. We want destructuring instead.

To show JavaScript that it’s not a code block, we can wrap the expression in parentheses (...) :

Nested destructuring

If an object or an array contains other nested objects and arrays, we can use more complex left-side patterns to extract deeper portions.

In the code below options has another object in the property size and an array in the property items . The pattern on the left side of the assignment has the same structure to extract values from them:

All properties of options object except extra that is absent in the left part, are assigned to corresponding variables:

Finally, we have width , height , item1 , item2 and title from the default value.

Note that there are no variables for size and items , as we take their content instead.

Smart function parameters

There are times when a function has many parameters, most of which are optional. That’s especially true for user interfaces. Imagine a function that creates a menu. It may have a width, a height, a title, items list and so on.

Here’s a bad way to write such a function:

In real-life, the problem is how to remember the order of arguments. Usually IDEs try to help us, especially if the code is well-documented, but still… Another problem is how to call a function when most parameters are ok by default.

That’s ugly. And becomes unreadable when we deal with more parameters.

Destructuring comes to the rescue!

We can pass parameters as an object, and the function immediately destructurizes them into variables:

We can also use more complex destructuring with nested objects and colon mappings:

The full syntax is the same as for a destructuring assignment:

Then, for an object of parameters, there will be a variable varName for property incomingProperty , with defaultValue by default.

Please note that such destructuring assumes that showMenu() does have an argument. If we want all values by default, then we should specify an empty object:

We can fix this by making {} the default value for the whole object of parameters:

In the code above, the whole arguments object is {} by default, so there’s always something to destructurize.

Destructuring assignment allows for instantly mapping an object or array onto many variables.

The full object syntax:

This means that property prop should go into the variable varName and, if no such property exists, then the default value should be used.

Object properties that have no mapping are copied to the rest object.

The full array syntax:

The first item goes to item1 ; the second goes into item2 , all the rest makes the array rest .

It’s possible to extract data from nested arrays/objects, for that the left side must have the same structure as the right one.

We have an object:

Write the destructuring assignment that reads:

• name property into the variable name .
• years property into the variable age .
• isAdmin property into the variable isAdmin (false, if no such property)

Here’s an example of the values after your assignment:

The maximal salary

There is a salaries object:

Create the function topSalary(salaries) that returns the name of the top-paid person.

• If salaries is empty, it should return null .
• If there are multiple top-paid persons, return any of them.

P.S. Use Object.entries and destructuring to iterate over key/value pairs.

Assignment (=)

The assignment ( = ) operator is used to assign a value to a variable or property. The assignment expression itself has a value, which is the assigned value. This allows multiple assignments to be chained in order to assign a single value to multiple variables.

A valid assignment target, including an identifier or a property accessor . It can also be a destructuring assignment pattern .

An expression specifying the value to be assigned to x .

Return value

The value of y .

Thrown in strict mode if assigning to an identifier that is not declared in the scope.

Thrown in strict mode if assigning to a property that is not modifiable .

Description

The assignment operator is completely different from the equals ( = ) sign used as syntactic separators in other locations, which include:

• Initializers of var , let , and const declarations
• Default values of destructuring
• Default parameters
• Initializers of class fields

All these places accept an assignment expression on the right-hand side of the = , so if you have multiple equals signs chained together:

This is equivalent to:

Which means y must be a pre-existing variable, and x is a newly declared const variable. y is assigned the value 5 , and x is initialized with the value of the y = 5 expression, which is also 5 . If y is not a pre-existing variable, a global variable y is implicitly created in non-strict mode , or a ReferenceError is thrown in strict mode. To declare two variables within the same declaration, use:

Simple assignment and chaining

Value of assignment expressions.

The assignment expression itself evaluates to the value of the right-hand side, so you can log the value and assign to a variable at the same time.

Unqualified identifier assignment

The global object sits at the top of the scope chain. When attempting to resolve a name to a value, the scope chain is searched. This means that properties on the global object are conveniently visible from every scope, without having to qualify the names with globalThis. or window. or global. .

Because the global object has a String property ( Object.hasOwn(globalThis, "String") ), you can use the following code:

So the global object will ultimately be searched for unqualified identifiers. You don't have to type globalThis.String ; you can just type the unqualified String . To make this feature more conceptually consistent, assignment to unqualified identifiers will assume you want to create a property with that name on the global object (with globalThis. omitted), if there is no variable of the same name declared in the scope chain.

In strict mode , assignment to an unqualified identifier in strict mode will result in a ReferenceError , to avoid the accidental creation of properties on the global object.

Note that the implication of the above is that, contrary to popular misinformation, JavaScript does not have implicit or undeclared variables. It just conflates the global object with the global scope and allows omitting the global object qualifier during property creation.

Assignment with destructuring

The left-hand side of can also be an assignment pattern. This allows assigning to multiple variables at once.
