AJAX is a technique that appeared in the late 1990s and early 2000s. The real revolutionary thing about it is that it used current technologies to do something extremely powerful and new: updating the content of your website without reloading the page.
Until then, if you wanted to update a simple button or the elements in your inbox, you would’ve needed to refresh the entire page. But reloading an entire page for only a single element is not very resource-effective.
What AJAX allows us to do is to update a particular part of your website with information from your server without refreshing the entire website.
