User experience is vital to the success of your website or web app. It’s important that the user’s experience be smooth and free of jank, yet the application will have to do things that take take a long time to complete. AJAX allows app developers to interact with server-side APIs without pausing script execution or forcing the page to reload.
Plus, learning how to query data APIs will open you to a tremendous amount of free data that’s freely accessible. Want to build a flight tracking app? How about a photo gallery with image search? Or what about a tweet viewer? Just find an API that provides the data you need, read the documentation and sample code, and query away!
If you want to build solid and fast web applications, knowing how to query servers using AJAX is a must.
