What’s JavaScript


    JavaScript is used as a high-level, dynamic, untyped, and interpreted programming language. Alongside HTML and CSS, it is one of the three essential technologies of World Wide Web content production.


Creative Dynamic Design


    JavaScript makes way for giving page effects which enhance the look and feel of a page. The dynamic effects such as rollover images and scripted slideshows are deftly created by JavaScript. JavaScript has the ability to create very dynamic image effects which will hook the users to a particular site. The flashy page effects added on the web page will intrigue the users to explore more on that particular website. JavaScript provides endless integration with user plug-ins.

Enhanced Functionality


    The JavaScript client-side mechanism provides many advantages over traditional CGI server-side scripts. For example, you might use JavaScript to check if the user has entered a valid e-mail address in a form field. The JavaScript code is executed when the user submits the form, and only if all the entries are valid, they would be submitted to the Web Server.


Speed


    As the code is executed on the user's computer, results and processing is completed almost instantly depending on the task (tasks in javascript on web pages are usually simple so as to prevent being a memory hog) as it does not need to be processed in the site's web server and sent back to the user consuming local as well as server bandwidth.
