JavaScript is an open-source, high-level, object-oriented, scripting language used to create interactive and dynamic web applications. Its ability to manipulate and interact with the DOM of a web page allows developers to modify pages in response to user interactions.

JavaScript, first named Mocha then LiveScript, was created in 1995 by Brendan Eich at Netscape for the company’s web browser, Netscape Navigator. It became popular for client-side web development.
