Need of Ajax

As I already describe, Ajax is not a programming language but Ajax used grouped of technologies (programming languages) to create interactive webpages and web applications.

1. Typical browsing behaviours consist of loading a web page then selecting some action that we want to do filling out a form submitting the info etc.
2. We works in sequential manner requesting one web page at a time have to wait for the server response.
3. Every time you request a new web page will be loaded.
4. Java Script is the way to cut down the response time by using it to verify information before submitted to the server.
5. One of the Java Script limitation is that there is no way to communicate directly with a web server.

This is also one of the limitation of the web pages, where transmitting information between client and server generally requires a new page to be loaded.
