What is JavaScript?

JavaScript is one of the popular programming languages that is used in most of the websites on the World Wide Web. It is also known as JS and is lightweight, cross-platform, and interpreted in nature.

Most of the time, JS is used to make webpages interactive and alive. For example, showing popups and changing page content when a button is clicked, validating users' emails on forms, and so on.

Basically, we can say that if you want to do anything related to websites and webpages, JavaScript is the language to go with.

Besides webpages, JavaScript is also used in game development, mobile app development, artwork creation, etc.

In short, it would be fair to conclude that javascript is the one language that rules the web.

History of JavaScript

JavaScript was created in 1995 by Brandan Eich, a Netscape programmer at that time. Initially, it was named Mocha and LiveScript. However, while taking the language public, it was named JavaScript.

The name was derived from the famous programming language Java to make it look more appealing.

Despite having a similar name, JavaScript has nothing to do with Java. It's an independent language with its own set of specifications. In recent times, JavaScript is also referred to as ECMAScript, and programs written in JavaScript are called scripts.
