What are the applications of JavaScript?

Overview

JavaScript has now become one of the most used programming languages in the world. It enables developers to make web pages more interactive and dynamic. Without it, almost all web pages would be static. Today, nearly all major platforms, like iOS, Android, macOS, Windows, and Linux, use JavaScript.

Why JavaScript?

JavaScript is famous because of its open-source repository. It has one of the largest open-source repositories (npm).

Some reasons for the popularity of this programming language are as follows:

  • It doesn't need any environment setup.
  • It runs on both the client and server-side.
  • It runs on most devices.
  • It allows front-end and back-end development
  • It has frequently updated versions.
  • It has open-source code.
  • It has extensive external libraries.

Applications

JavaScript has numerous applications in various fields. Some of the main applications of JavaScript are as follows:

Web development

JavaScript is a scripting language developed in Netscape, and used for creating online web pages. It allows developers to make pages more dynamic. It also helps developers add special effects like hover, animations, rollout, etc. JavaScript helps the web server to reduce its processing load and time, and performs front-end validations on the client-side. Moreover, JavaScript helps run small external applications like PDF viewers.

Presentations

We can use JavaScript to make interesting presentations. The reveal.js and bespoke.js libraries help developers make web-based sliders. They are so beginner-friendly that even if a person has no programming knowledge, they can make presentations with just a little online help. They support all CSS formats and have different transition effects. WebGL is also a JavaScript library that can render two-dimensional and three-dimensional images to help make presentations.

Server applications

The Node.js library provides the environment and necessary tools to create server applications. These tools help developers establish the environment necessary for JavaScript to run servers. JavaScript generates HTTP request handlers and helps us create web servers.

Games

Developers can build games just using HTML5 and JavaScript. EaselJS is a JavaScript library that helps us build games. It is a simple API that provides the scene of the game. It also has two-dimensional bitmaps that can be drawn on the canvas of the scene.

Art

With HTML5 and JavaScript, developers can draw all kinds of two-dimensional and three-dimensional shapes on the canvas. They can view these on any browser.

Smartwatch applications

We can use the pebble.js library to make smartwatch applications. It has multiple dimensions of smartwatches' screens.

Mobile applications

We can use JavaScript to develop a full-fledged mobile application without web context. With the help of React Native, developers can now make applications for both Andriod and iOS with a single code. React Native uses Node.js to build JavaScript code.

Flying robots

Developers can now code programs that help drones fly from one place to a particular destination with the help of the Node.js library.
