AJAX and JavaScript

Question

Write about the AJAX and JavaScript?

Answer 1

a) AJAX requests the server and does not wait for any response. It carry out other operations on the page during that time while JavaScript requests to server and waits for the response.

b) AJAX does not require the page to be refreshed in order to download the whole page while JavaScript controls and manages a Web page after it is downloaded.

c) AJAX decreases the overload over the server as the script needs to request once on the other hand JavaScript posts a request which updates script every time.
