In this tutorial, you will learn about the various uses of JavaScript.

What is JavaScript?

JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make site pages interactive. Where HTML and CSS are languages that give structure and style to website pages, JavaScript gives web pages interactive elements that engage a user.

Incorporating JavaScript improves the user experience of the website page by changing over it from a static page into an interactive one. To recap, JavaScript adds behavior to website pages.

JavaScript is quite possibly the most popular programming language because of its wide range of applications.

Before JavaScript was essentially used in:

  • making web pages interactive
  • Nowadays, JavaScript is also used in:
  • server-side applications
  • game development
  • mobile apps
  • web-apps

Now let’s explore the uses of JavaScript in more detail.

1. Making The Web Pages Interactive

JavaScript is used to make the web pages interact with the user with different functionalities, for example,

  • From validation, for example, checking if an email design is right or not
  • Showing a countdown clock
  • Interactive maps
  • Making cool animations
  • Various activities on the press of the catch
  • Use of dropdown menu

There are numerous alternative ways where JavaScript is used in making the website pages interactive.

2. Making Server Side Applications

JavaScript is additionally used as a server-side language to build back-end development using node.js (a JavaScript runtime environment built on Google Chrome’s JavaScript V8 engine).

The Node.js provides an environment for JavaScript to run on servers.

Before JavaScript was just used for making the site pages interactive. In any case, the use of JavaScript node.js is acknowledged as a decent alternative for back-end development also.

Organizations like LinkedIn, Netflix, Uber, Trello, PayPal, NASA, eBay, Medium use node.js to control their applications.

3. Making Interactive Front-End Pages

One of the developing uses of JS these days is making overly interactive front-end applications. For this, the generally used JavaScript frameworks are React, Vue and Angular.

These applications load the resources as soon as the site is loaded which results in quick and responsive user interaction with a great user experience.

A few instances of single-page applications are Facebook, Google Maps, Gmail, Twitter, and so on

Different JavaScript frameworks, for example, Angular, React, MeteorJs, BackboneJs, EmberJs, PolymerJs, KnockoutJs, Aurelia could be used as the front-end innovation to build interactive front end pages.

Two popular frameworks used for front-end application development are Angular and React.

Note: Angular is created by Google and React is created by Facebook. Consequently, we can expect good and long support for this framework.

4. Making Mobile Applications

JavaScript is additionally used in making Android and iOS applications. React Native is a popular framework build on JavaScript for this reason.

One thing that is especially intriguing about React Native is that we can make both Android and iOS applications from the equivalent codebase. This helps in:

  • quicker development time
  • simple to create
  • cost-effective

A portion of the popular applications created in react native are Facebook Ads, Walmart, Bloomberg, Instagram, Gyroscope, UberEats, Discord, and some more.

Note: React Native is created by Facebook. Henceforth, we can expect good and long support for this framework.

5. Game Development

JavaScript is likewise used for game development.

Different JavaScript libraries, for example, Three.js, TweenMax could be used to create browser games.

A few libraries even allow you to export your games into different platforms, for example, Android, iOS, and so forth
