JavaScript

JavaScript is a high-level, interpreted programming language that is a core technology of the web, enabling interactive and dynamic content in web browsers. It is widely used for client-side scripting, server-side development (via Node.js), and mobile app development, supporting object-oriented, imperative, and functional programming styles.

Also known as: JS, ECMAScript, ES6+, Vanilla JS, Modern JS
