What is AJAX?

AJAX = Asynchronous JavaScript And XML.

AJAX is not a programming language.

AJAX just uses a combination of:

• A browser built-in XMLHttpRequest object (to request data from a web server)
• JavaScript and HTML DOM (to display or use the data)

• This JavaScript function can be used to demonstrate the use of AJAX.
•  function loadDoc() {
•   const xhttp = new XMLHttpRequest();
•   xhttp.onload = function() {
•     document.getElementById("demo").innerHTML = this.responseText;
•     }
•   xhttp.open("GET", "ajax_info.txt", true);
•   xhttp.send();
• }
