Demystifying Ajax

Ajax is a technology that allows web pages to dynamically perform actions or updates. This allows for a higher level of user interactivity that we can see in popular applications such as Google Maps or Gmail.

Since its introduction in 2005, Ajax has stood out as an excellent addition to the web developer's arsenal, but several developers have been reluctant to use it due to certain initial problems and cross-browser compatibility issues.

Fortunately, today these issues are gone thanks to high-level libraries such as jQuery that take care of all Ajax calls internally and give us a simple to use API.
