JavaScript
JavaScript is a programming language created at Netscape in 1995 and widely used to add interactive behavior to web pages.
JavaScript is a programming language created by Brendan Eich at Netscape in 1995. On the web, HTML defines a page's structure and CSS its appearance, while JavaScript implements behavior such as button responses and changes to displayed content. It is standardized as ECMAScript and, despite its name, is unrelated to Java.
It also runs outside browsers in environments such as Node.js, with packages managed through npm. Developers use it with tools such as React and Vite to build web apps.
