Definition: Javascript is a scripting language that was designed to give web pages the ability to interact with the people viewing them. Examples of such interaction include performing actions in response to mouse movement or mouse clicks and validation of what has been entered into forms. Javascript is made up of the core language (also known as ECMAscript), the Document Object Model (which allows interaction with the web page), and the Browser Object Model (which allows limited interaction with the browser).
Also Known As: ECMAscript
