AJAX

AJAX stands for Asynchronous JavaScript And XML. In a nutshell, it is the use of the XMLHttpRequest object to communicate with servers. It can send and receive information in various formats, including JSON, XML, HTML, and text files.An event occurs in a web page (the page is loaded, a button is clicked)

An XMLHttpRequest object is created by JavaScript.

*The XMLHttpRequest object sends a request to a web server.

*The server processes the request.

*The server sends a response back to the web page.

*The response is read by JavaScript.Ajax is gradually being replaced by functions within JavaScript frameworks and the official Fetch API Standard.
