Tech 101: AJAX—What It Is, How It Works, and What It’s Used For
It’s all about those asynchronous updates.
As your quest to tackle tech jargon continues, you’ll eventually come across the term AJAX. In technology terms AJAX has nothing to do with cleaning products or overly-muscled Trojan War veterans (which is probably obvious), but what does it refer to? Is it a programming language? A software platform? A web application? The answer is actually none of the above.
What Is AJAX?
One of the most ubiquitous examples of asynchronous updating is Google’s “Google Suggest” feature. When you enter a search query into Google’s search bar and the Google website automatically begins offering auto-complete options while you type, that’s AJAX in action. The content on the page changes (in this case, the auto-complete options in the search bar) without having to manually refresh the page (something that would make Google Suggest impractical to use). Features like Google Suggest are a fundamental part of contemporary web browsing, which points to how essential AJAX is in web development. In addition to Google Suggest, Cascarano says that AJAX is commonly used to update features like status and notification bars, online forms, comments sections, and surveys and polls. But what exactly are the “J” and “X” of AJAX and how do they make asynchronous updating possible?
