Overview of JavaScript

JavaScript was created by Brendan Eich at Netscape Navigator 2.0 and was first introduced in December 1995 under the name of Live Script. However, it was rather quickly replaced with the name JavaScript, although the JavaScript’s official name is ECMAScript, and it is developed and maintained by the ECMA (European Computer Manufacturer’s Association) International organization.

JavaScript is a scripting language, i.e. it is a lightweight programming language that is interpreted by the browser engine when the web page is loaded.


JavaScript may be used in Website development to do such things like:

  • Automatically changes a formatted date on a Web page.
  • Create a linked-to page to appear in a popup window.
  • Make text or a graphic image to change during a mouse hover on it.
  • Put text in an HTML page on-the-fly.
  • Make your web pages responsive.
  • Detect visitors’ browsers.
  • Create cookies.
  • Validate web form data.

JavaScript is widely supported in following web browsers:

  • Netscape Navigator (beginning with version 2.0)
  • Microsoft Internet Explorer (beginning with version 3.0)
  • Firefox
  • Safari
  • Opera
  • Google Chrome
