What is JavaScript?

JavaScript (JS) is a high-level, interpreted programming language that conforms to the ECMAScript specification. It is primarily used in web development to add interactivity and dynamic behavior to static HTML pages.

JavaScript was initially introduced in 1995 as a way to add programmability to web pages, but it has evolved significantly over time. Today, JavaScript can be used on both the client-side (front-end) and server-side (back-end) of web development through Node.js, a JavaScript runtime environment.

Why is JavaScript used for the web?

Browser Compatibility: JavaScript is the only language that runs natively in all web browsers. This compatibility ensures a wide reach and makes it a universal scripting language of the web.
