What is JavaScript?

JavaScript is the most commonly used scripting language. JavaScript is developed by Netscape. JavaScript is supported in most browsers. It allows code to be directly embedded in HTML markup. It adds interactivity to web pages. There are different ways in which script can be added with HTML documents. This language has all the features of most popular programming language.

Scripts can perform many functions such as, validating user input, generating dynamic content, doing simple calculation, handle events made by the user, alerting users with message etc. It is similar in coding to the java Programming Language. Hence the name JavaScript. But it has no direct relation to the Java Programming language. Java is a object oriented programming language that can be used to create stand alone programs and applets. Java Script is an interpreted object – based platform – independent scripting language. JavaScript is platform independent because the scripts are interpreted by the browser. JavaScript recognizes the elements of a web page and properties of the browser itself through a object – based architecture. This object based architecture is called Document Object Model.  ( DOM )
