Use Google's JavaScript API loader to speed up your site's _javascript skills

If your site uses some of the mainstream Ajax library such as jquery or prototype, you can use Google Javascript API loader to load your AJAX library directly.
The specific approach is the following example:
<script src= "Http://www.google.com/jsapi" language= "javascript" ></script> <script language= " JavaScript "> Google.load (" Prototype "," 1.6 ");
</script>
Because Google uses a CDN (content distribution network) to send data to clients faster than your server, and the client browser caches content based on links, the more sites that use Google Javascript API loader, The greater the chance of client-side cache hits.
Google's Ajax Library API now supports most of the mainstream Ajax frameworks:
Jquery
JQuery UI
Prototype
Script.aculo.us
MooTools
Dojo

Yahoo! User Interface Library (YUI)
