AJAXAsynchronous JavaScript And XML is a set of web development techniques that use many web technologies on the client-side to create asynchronous web applications. With Ajax, web applications can asynchronously send and retrieve data from a server without interfering with the existing page’s display and behavior. It is not a programming language and it requires a built-in browser with a XMLHttpRequest object that requests data from the server. It also uses JavaScript and HTML DOM to display data.

Google APIs contain many google hosted libraries. This is a widely available global content distribution network for the most commonly used JavaScript libraries.

Load libraries from the CDN via HTTPs to make sure performance using caches is not compromised.

Let’s look at some examples:
