Answer 1

Hello, Sergo 93 !
AJAX, Ajax - an approach to building interactive user interfaces for web applications, which consists in the "background" exchange of browser data with a web server. As a result, when you update the data, the web page does not completely restart, and web applications become faster and more convenient.

AJAX allows you to send and receive data without refreshing the page. For example, if you wanted to get data from a PHP form. normally, you'd need to redirect the user to the page which would require a refresh. With AJAX, you can do this all in the background. The user wouldn't even notice.
