It's all about user-friendly.
Without AJAX, to get or send information from/to a database or a file on the server with traditional JavaScript, your user will have to trigger certain action like clicking the "Submit" button to send/get the information, wait for the server to respond, then a new page will load with the results. Because the server returns a new page each time the user submits input, traditional web applications can run slowly and tend to be less user-friendly.
With AJAX, your JavaScript communicates directly with the server, a web page can make a request to, and get a response from a web server - without reloading the page. The user can stay on the same page without noticing that scripts request pages, or send data to a server in the background.

What's AJAX?
AJAX stands for Asynchronous JavaScript and XML.
With AJAX, a JavaScript can communicate directly with the server, with the XMLHttpRequest object. With this object, a JavaScript can trade data with a web server, without reloading the page.
AJAX uses asynchronous data transfer (HTTP requests) between the browser and the web server, allowing web pages to request small bits of information from the server instead of whole pages.
The AJAX technique makes Internet applications smaller, faster and more user-friendly.
