About JS Files

.js Icon

A .js file is a text file that stores JavaScript code, which programmers use to create dynamic and interactive elements on websites. Examples of interactivity they enable include responding to user inputs, animating elements, managing multimedia, and fetching data without reloading the page. Beyond web development, .js files are also used in server-side programming through environments like Node.js.

Brendan Eich developed JavaScript in 1995 while working at Netscape Communications Corporation. The language was initially called "Mocha," then "LiveScript," and then renamed to "JavaScript" because of the growing popularity of Java, although the languages are unrelated. ECMA International then standardized it through the ECMAScript specification, ensuring compatibility and adoption across web browsers. Now, JavaScript is one of several languages that form the foundation of modern web development, along with HTML and CSS.

When viewing and modifying .js files, developers often use source code editors, which provide helpful features like syntax highlighting. They may also use text editors, but they do not offer code-editing features available with code editors.
