What is JavaScript Used for?

JavaScript is a scripting language used to develop web pages, essential for creating interactive and dynamic user experiences online. Regardless of your familiarity with the term, you’ve likely engaged with features fully or partially powered by JavaScript, from simple animations to complex web applications.

This language’s versatility extends to various uses, including animating web page elements, validating form inputs, fetching and displaying data without refreshing the page, and building sophisticated web applications that operate seamlessly across devices. But what specific functionalities does JavaScript enable?

Let’s explore the types of things that JavaScript developers can accomplish and how they can help your business.

JavaScript’s Many Uses

JavaScript has remained a popular language due to its many applications. Let’s go over the most common JavaScript uses.

1. Interactive Websites

Before JavaScript, web pages were confined to basic HTML and CSS, making them static and lacking interaction outside of following hyperlinks.

JavaScript’s purpose for being developed was to provide web pages with a way to be dynamic. With its adoption, web pages became able to change content on the fly, add animations to elements, and play media such as music and video.

The main use of JavaScript is web development. It is used ubiquitously, and the World Wide Web wouldn’t exist as it is today without it.

2. Applications

An extension of websites, web applications also became very popular in recent years. Their ability to be used in browsers anywhere, no matter the platform, has made them an attractive option for developers looking for cross-platform mobile development.

Over the years, many JavaScript frameworks have surfaced to help developers create their applications and publish them to the web faster. Some examples include:

  • AngularJS
  • React
  • Vue.js
  • Node.js
  • Ember.js
  • Svelte
  • Meteor

Most of these are focused on creating a front end for the application, but Node.js is a notable entry since it allows developers to create a back-end. This is important since it allows a web application to be fully developed using JavaScript solely as the programming language.

React also has React Native, which lets you use React primitives to develop native mobile applications. If you’re looking to develop a web application with the possibility of eventually developing native mobile versions, React is a great choice.

3. Games And Other Virtual Experiences

As web browsers are becoming ever more powerful in terms of rendering capabilities, graphics-heavy applications that were previously hard to run on a browser are becoming easier than ever to develop and deploy.

Frameworks such as Phaser have allowed game developers to create 2D interactive experiences that can run in the browser. As for JavaScript examples for 3D development, Three.js (library) and A-Frame (framework) are some popular options. These can also be used to make games and even AR and VR experiences.

Why Use JavaScript? Is it Really Needed?

JavaScript provides many features that make it extremely useful when dealing with dynamic content, which is a staple of modern web pages and applications. That’s why it remains as the most popular language, according to StackOverflow’s users, for both professional and hobby use.

It is especially important if you want to create any sort of dynamic web content. Despite its web-based origins, it has become a universal language that has many applications, and that can be used in just about any programming project.

The Pros and Cons of JavaScript

Simple and easy to learnNot easy to debug
Fast, interpreted languageLow client-side security
Works well with other languagesLacks support for multiple inheritance
Lowers server load by working client-sideIt can work differently depending on the browser being used


JavaScript is an especially important language for web development, but it also has many uses outside of it. For that reason, it’s essential for any business to have someone or even a team proficient in JavaScript.
