What is JavaScript used for?

JavaScript is widely used for web-based applications and web browsers. But JavaScript is also used across the Web for embedded software, servers and embedded hardware controls. Here is some uses of javascript.

Adding interactive behavior to web pages

JavaScript allows users to interact with web pages. There are almost no limits to what you can do with JavaScript on a web page – here are just a few examples:

  • Show or hide more information by clicking the button
  • Change the color of the button as the mouse moves around
  • Slide into carousel pictures on the homepage
  •  Animate & resizing an image
  • Displaying the timer or countdown on the website
  • Plays audio and video on a web page
  • Shows animation
  • Using the drop-down hamburger menu

Creating web and mobile apps

Developers can use different JavaScript frameworks to develop and build web and mobile applications. JavaScript frames are collections of JavaScript codecs that provide developers with pre-coded code for use in programmatic features and functions — which is a real framework for building websites or web applications around.

Popular previous JavaScript frameworks include React, React Native, Angular, and NodeJs Many companies use Node.js, a JavaScript workspace built into the JavaScript V8 engine of Google Chrome.

Game development

Of course, you can also use JavaScript to create browser games. This is a great way for beginner developers to practice their JavaScript skills.



JavaScript Restrictions

We cannot treat JavaScript as a full edit language. It does not have the following key features –

JavaScript client side does not allow reading or writing files. This is reserved for security reasons.

JavaScript cannot be used for network applications because no such support is available.

JavaScript does not have the ability to add multiple or multiprocessors.

Once again, JavaScript is a simple, interpreted programming language that allows you to build interaction with static HTML pages.
