What Is Javascript Used For? | Key Uses Of Javascript
Have you ever asked, ‘what is JavaScript used for?’ Many people are confused by the same question. JavaScript is used for many purposes. We will discuss the key uses of Javascript in real life.
Javascript is used worldwide by programmers to create interactive and dynamic web content such as browsers and applications. JavaScript is the most popular programming language worldwide. It’s used by 97.0% of all websites as a client-side language. Client-side languages are those that take place on the client’s computer and not on the server.
JavaScript can be used in a wide variety of applications including software, servers, and hardware controls. JavaScript is a web-based language that’s native to web browsers. The language can be understood by the web browser in the same way that native English speakers can understand English.

What Is JavaScript?
JavaScript is a text-based computer language that can be used on both the client and server sides to create interactive web pages. Unlike HTML and CSS, which provide web pages structure and design, JavaScript allows web sites to be interactive. JavaScript is a programming language that you may encounter on a daily basis. It may be used to search Amazon, update your Twitter feed, and embed New York Times news recap videos.
What is JavaScript used for?
JavaScript can be used by any industry to create many types of applications. Let’s look closer at JavaScript’s uses in web, mobile, and game development.
Front-end web development
JavaScript is used by front-end developers along with HTML and CSS to create web pages that users can interact with in their browsers.
Web pages used static content before JavaScript. JavaScript allowed developers to create dynamic web experiences for their users by adding animations or other interactive elements. JavaScript is at work when a button is clicked on a website. A side panel will open or a modal slowly appears.
JavaScript is more than just a web browser. JavaScript can be used to create single-page apps (or SPAs), which run on one HTML webpage to provide smooth navigation.
Back-end web development
Back-end developers also love JavaScript. Back-end web development, also known as server-side programming, involves the creation of code that runs on a server. A browser calls a remote server when it loads a page. The server-side code parses the URL of the page to determine the request made by the user. After retrieving the data, the server transforms it to be returned to the browser.
Node.js, a JavaScript framework that is commonly used for back end development, is so popular that many JavaScript developers refer to themselves as Node.js experts.

Game development
JavaScript can be used to create 2D or 3D games that work in web browsers. Web-based games have evolved beyond being simple platformers as browsers become more powerful. JavaScript frameworks such as Phaser.js make it possible to quickly create advanced games right from your browser.
Mobile development
Mobile developers were forced to choose between iOS and Android for years because each platform has its own programming languages. Android developers would have to learn Java or Kotlin while iOS developers preferred Swift or Objective-C.
With the rise in mobile development frameworks such as Ionic and React Native, JavaScript can be used to create apps that work on both iOS and Android.
Virtual reality (VR)
With gadgets like the Oculus Rift and the Valve Index making virtual reality more accessible, it’s back in style. You can now use JavaScript to make applications for either of these devices.
A-Frame, a JavaScript framework that allows you to create virtual reality experiences using web browsers, is very popular. Learn A-Frame if you are interested in creating your own VR apps.
Artificial intelligence (AI).
JavaScript can also be used to create artificial intelligence. Libraries like TensorFlow provide the power of machine-learning to JavaScript developers. These libraries can be used by developers to build machine learning models that use past data to predict future events and classify data and images.
Last words
JavaScript is more than a web browser-friendly programming language. JavaScript is a powerful, well-respected language that has risen to the top of the popularity charts for the last three decades. JavaScript’s flexibility and broad range of applications makes it an invaluable addition to any developer’s tech stack. JavaScript’s basics are explained in this introduction.
