All Javascript Libraries are already installed on their server, so all you need to do is create a <script></script> tag with inside <noautolink> of your page and you should be able to load any of the available modules. Once you’ve loaded them, close the script tag out, and use a separate script block for using the API.

JSLoader supports many Javascript Framewroks, and is beeing regularly updated. So far it offers dynamic embedding of Dojo, Ext.js, FCKEditor, JQuery, MochiKit, PlotKit, Google Prettify, Prototype.js, Scriptaculous, SWFUpload, TinyMCE and YahooUI.
