MediaWiki/js
The first thing to know about MediaWiki and JavaScript is that the site administrator can customize the wiki installation by simply modifying the article MediaWiki:Common.js
For instance, if you put the JavaScript code for wikEd in there, it will make the WikEd editor available to all users of the local wiki.
