JavaScript ("JS" for short) is a lightweight, interpreted or just-in-time compiled programming language with function priority. Although it is famous as a scripting language for developing Web pages, it is also used in many non-browser environments. JavaScript is based on prototype programming, a multi-paradigm dynamic scripting language, and supports object-oriented, imperative, declarative, and functional programming paradigm.

JavaScript is a network scripting language that has been widely used in Web application development. It is often used to add various dynamic functions to web pages to provide users with smoother and more beautiful browsing effects. Usually JavaScript scripts realize their functions by embedding them in HTML.

JavaScript was developed for Netscape. Netscape 2 was the first browser to run JavaScript.

After Netscape, the Mozilla Foundation continued to develop JavaScript for the Firefox browser.

The latest JavaScript version is 1.8.5. (Same as ECMAScript 5).

ECMAScript was developed by ECMA International after the organization adopted JavaScript.

The first version of ECMAScript was released in 1997.
