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.
