AJAX Tutorial


AJAX = Asynchronous JavaScript and XML.

AJAX is not a new programming language, but a new method that uses existing standards.

The biggest advantage of AJAX is that it can exchange data with the server and update part of the web page content without reloading the entire page.

AJAX does not require any browser plugins, but requires the user to allow JavaScript to execute in the browser.

XMLHttpRequest is just one way to implement Ajax, of course you can also usefetch APIand other modern methods.
