What is JavaScript?

JavaScript (“JS” for short) is a full-fledged dynamic programming language that can add interactivity to a website.

JavaScript is versatile and beginner-friendly. With extra experience, you will be capable to create games, animated 2D and 3D graphics, comprehensive database-driven apps, and a whole lot more!

JavaScript itself is fairly compact, but very flexible. Developers have written a range of tools on top of the core JavaScript language, unlocking a large amount of functionality with minimal effort. These include:

Browser Application Programming Interfaces (APIs) built into web browsers, offering functionality such as dynamically creating HTML and placing CSS styles; collecting and manipulating a video stream from a user’s webcam, or generating 3D graphics and audio samples.

Third-party APIs that enable developers to include functionality in websites from other content material providers, such as Twitter or Facebook.

Third-party frameworks and libraries that you can apply to HTML to speed up the work of developing websites and applications.
