What does XMLHttpRequest do?

The XMLHttpRequest Object is an API that can be used by JavaScript, JScript, VBScript, and other web browser scripting languages. It allows the transfer of data between a web browser and a web server. It is supported by most modern browsers.

The XMLHttpRequest allows one to update parts of a web page, without reloading the whole page, which can be very useful at times. It also allows one to request data from a server even after the page has loaded, as well as receive data from a server after the page has loaded. One can also send data to a server in the background.
