JS File Format

JS is a file extension for a JavaScript source code file format.

JavaScript is used in Web development to do such things as:

• Automatically change a formatted date
• Cause a linked-to page to pop up in a new window
• Cause text or an image to change during a mouse rollover

A JS file is used mainly to run client side JavaScript code on a webpage. The JS file contains all the HTML HEAD and BODY objects in the tags of an HTML page.

MIME type: application/x-javascript, text/javascript
