What are the differences between AJAX and JavaScript?

The differences between AJAX and JavaScript are given as follows:

•     AJAX sends request to the server and does not wait for the response. It performs other operations on the page during that time. JavaScript make a request to the server and waits for response.

•     AJAX does not require the page to refresh for downloading the whole page while JavaScript manages and controls a Web page after being downloaded.

•     AJAX minimizes the overload on the server since the script needs to request once while JavaScript posts a request that updates the script every time.
