advantages of javascript

An advantage in using JavaScript is that it allows web pages to be interactive even when they are not connected to the internet. One major use of web-based JavaScript is to write functions that are embedded in or included from HTML pages and interact with the Document Object Model (DOM) of the page to perform tasks not possible in HTML alone. Some common examples of this usage are:

• Opening or popping up a new window with programmatic control over the size, position and 'look' of the new window;
• Checking or validating web form input values to make sure that they will be accepted before they are submitted to the server;
• Changing images as the mouse cursor moves over them;
