Ajax

AJAX vs Fetch API: what should you use today?

The question is about Ajax .

Answer:

Classic AJAX, meaning requests made through XMLHttpRequest, is legacy at this point: every major browser has supported the newer Fetch API natively since 2017, and Fetch paired with async/await is the default way modern JavaScript makes asynchronous requests. AJAX itself isn't a rival technology to Fetch; it's the general pattern of updating a page without a full reload, and XMLHttpRequest was just the original tool used to do it.
