JAVASCRIPT PAGE
I have been using JavaScript ever since I started writing HTML web pages in 1999. It is a very common and useful client side scripting language. There have been some issues with the browser and version compatibility of JavaScript, but for the most part is a decent cross platform language.
My initial use of JavaScript was form validation and dynamic menu. I have also used the language for browser and plug-ins sniffers, mostly to detect the presence of a compatible flash player.
With the growing popularity of Ajax, I have been using JavaScript frameworks that contain Ajax functionality, mostly JQuery and DoJo. Ajax enables you to create faster and more intuitive web interfaces by utilizing the he XMLHttpRequest object for asynchronous communication. There are some drawbacks in your browsers’ history functionality and availability of content for search engine bots, but I think that the benefits outweigh the disadvantages.
