JavaScript

Javascript is a computer programming language that is frequently embedded within HTML pages on the World Wide Web. Javascript is not the same as Java, although its syntax is remarkably similar. Javascript code can be embedded in HTML pages. Web browsers will then execute the Javascript before displaying the web page for the user, or in response to user actions on the page, unless Javascript has been disabled in the web browser's options. Javascript is standardardized by the European Computer Manufacturer's Association (ECMA) and is, these days, occasionally referred to as ECMA-script.
