This lesson is part of PHP · All levels

Summary

AJAX (Asynchronous JavaScript and XML) allows web pages to send and receive data to a server in the background without reloading the entire page. Thus, certain sections such as the list of recommendations or user information can be updated while user interaction remains smooth. Despite its XML name, modern data is more often formatted as JSON.
