Uses of JavaScript

Let’s see how application of JavaScript is being used in various sectors:

1. Web Applications

JavaScript has become increasingly popular for building dependable web apps because browsers are getting better every day. We may comprehend it by using Google Maps as an example. Users of Maps only need to click and move the mouse to reveal the details; clicking makes them visible. Not to mention, the idea behind these ideas is the use of JavaScript.

2. Web Development

It is a common practice to use JavaScript for web pages. Thanks to it, we can add dynamic behavior and additional effects to the website. Websites use JavaScript primarily for validation. JavaScript facilitates interaction between websites and their visitors as well as the execution of sophisticated actions. It is also feasible to load the information of a document using JavaScript without having to restart the website.

Nowadays, people commonly use mobile devices to access the internet. With JavaScript, we can create applications that are not web-based. JavaScript is an effective tool for developing mobile applications because of its capabilities and applications. React Native is a JavaScript framework that is very popular for building mobile applications. We can create mobile applications for several operating systems using React Native. Building separate code for the iOS and Android OS is unnecessary for our approach. But with JavaScript developers can write code for once and implement it for all systems.

Games can also be made with JavaScript. For making games, it includes a variety of libraries and frameworks. The game is available in 2D or 3D. We can build a web game with some JavaScript game engines, such as PhysicsJS and PixiJS. We may also utilize the JavaScript API known as WebGL to render 2D and 3D pictures on browsers.

5. Server Applications

Many web applications feature a server-side component. Developers make use of JavaScript to create content and manage HTTP requests. Node.js allows JavaScript to operate on servers as well. This framework offers a server environment with all the tools required to run JavaScript.

6. Presentations

We may also develop presentations as websites with JavaScript. It is possible to create a slide deck for the internet using libraries like RevealJs and BespokeJs. We can quickly create something extraordinary because they are simpler to utilize. It is possible with Reveal.js to create interactive and visually stunning PowerPoint decks using HTML. Tablets and mobile devices both easily accommodate these presentations. Bespoke.js also supports any CSS color format, responsive scaling, Animated bullet lists, and much more.

7. Web Servers

Developers use Node.js to build a web server. Node.js does not wait for the outcome of a prior request because it is event-driven. The servers built using Node.js are quick, don’t buffer, and transport data in chunks. The developer can use the createServer() method of the HTTP package to create the server. Whenever anyone attempts to connect to port 8080, this procedure runs. The HTTP server must respond by displaying HTML and returning an HTTP header.
