Definition

Meaning

A high-level, dynamic programming language used primarily to create interactive and dynamic content on websites.

A widely-used scripting language that conforms to the ECMAScript specification. It is a core technology of the World Wide Web, alongside HTML and CSS, enabling client-side script to interact with users, control browsers, and create asynchronous applications.
