About Javascipt

Javascript is used in millions of webpages to improve the design, validate forms, detect browsers and create cookies. Javascript is very popular scripting language on internet and works on almost all browsers like Mozilla Firefox, Opera, Internet Explorer, etc. It is usually embedded directly into HTML pages. Javascript coding is also used in making web pages. Javascipt is a scripting language with a very simple syntax. We can put small pieces of codes into their HTML pages. It can be set to execute when something happens like when a user clicks on an HTML element. It can also read and change the content of HTML element. It can be used to  validate form data before it is submitted to a server. It can be used to store and retrieve information on the visitor's computer.  Browsers that donot support javascript will display it as a page content. Javascript is a sequence of statements to be executed by the browser. Javascript statement is a command to the browser. The purpose of the command is to tell the browser what to do. In my opinion Javascript is very useful scripting language.
