What is the difference between AJAX applications and traditional Web applications?

please tell me

Or to send client information to the server, you need to create an HTML form and then GET or POST the data to the server.

Users need to click the "Submit" button to send or receive data information, and then wait for the server to respond to the request and the page to reload.

Because the server returns a new page every time, traditional web applications can be slow and user-unfriendly.

Using AJAX technology, Javascript can interact directly with the server through the XMLHttpRequest object.
