Many of the programmers might have a problem of keeping themselves updated with the latest versions of the famous AJAX and JavaScript libraries.
Everytime the user refreshes the page, a file 30KB long is sent again and again to the same user, increasing the server load and frustrating the user about the slow page load times. Many programmers are smart enough to send the proper headers but some like me… are not. Google thankfully understood our problems and worked up to solve it. And they have solved it, really!

AJAX Libraries API as Google says is a content distribution network. From the official page-

The AJAX Libraries API is a content distribution network and loading architecture for the most popular open source JavaScript libraries. By using the Google AJAX API Loader’s google.load() method, your application has high speed, globaly available access to a growing list of the most popular JavaScript open source libraries including:

• jQuery
• jQuery UI
• Prototype
• script.aculo.us
• MooTools
• Dojo

Google works directly with the key stake holders for each library effort and accept the latest stable versions as they are released. Once we host a release of a given library, we are committed to hosting that release indefinitely.

The AJAX Libraries API takes the pain out of developing mashups in JavaScript while using a collection of libraries. We take the pain out of hosting the libraries, correctly setting cache headers, staying up to date with the most recent bug fixes, etc.

This is most useful when you are deploying applications to the public. It can be a pain releasing a new version just for updating the JS libraries.

Some of my future posts will contain ideas to spice up your blog and make it rock in the blogosphere with a little PHP, JavaScript and AJAX.
