JavaScript is a programming language that can make web pages interactive and dynamic.
It was created in 1995 by Brendan Eich, who was working at Netscape at the time. He wanted to create a language that was easy to use and could run in the browser without needing a compiler
JavaScript is based on the ECMAScript standard, which defines the syntax and features of the language.
There are many versions of ECMAScript, and the latest one is ECMAScript 2021
JavaScript can also use additional features and libraries that are not part of the standard, such as the Document Object Model (DOM), which allows JavaScript to manipulate HTML elements on the page
What is JS is used for
JavaScript is used for many purposes, such as creating web applications, games, animations, data visualization, server-side programming, and more.
It can run on any device that has a JavaScript engine, which is a program that interprets and executes JavaScript code.
Some examples of JavaScript engines are V8 (used by Chrome, Opera, and Edge), SpiderMonkey (used by Firefox), and JavaScriptCore (used by Safari)
