JavaScript

Javascript is a computer programming language that is frequently embedded within HTML pages on the World Wide Web to make the page more interactive. Javascript is not the same as Java, although its syntax is remarkably similar. When Javascript code is embedded in HTML pages, Web browsers will then execute the Javascript before displaying the web page for the user. The Javascript within HTML may also execute in response to user actions on the page. Since in some cases Javascript may be disabled in the web browser's options, HTML pages must be functional even if the Javascript within them is not allowed to execute. Javascript is standardardized by the European Computer Manufacturer's Association (ECMA) and is, these days, occasionally referred to as ECMA-script.
