JavaScript
The Language of the Web
JavaScript is the most popular programming language in the world. It powers interactive websites, web applications, servers, mobile apps, and even desktop software.
What is JavaScript?
JavaScript is a programming language that runs in web browsers. It was created in 1995 and has become the backbone of modern web development. Every website you visit uses JavaScript in some way.
Unlike HTML (which structures content) and CSS (which styles it), JavaScript makes websites interactive. It can respond to clicks, validate forms, create animations, fetch data, and much more.
