MediaWiki:Common.js

/* Any JavaScript here will be loaded for all users on every page load. 
 Keep code in MediaWiki:Common.js to a minimum as it is unconditionally
 loaded for all users on every wiki page. If possible create a gadget that is
enabled by default instead of adding it here (since gadgets are fully
optimized ResourceLoader modules with possibility to add dependencies etc.)

 Since Common.js isn't a gadget, there is no place to declare its
 dependencies, so we have to lazy load them with mw.loader.using on demand and
 then execute the rest in the callback. In most cases these dependencies will
 be loaded (or loading) already and the callback will not be delayed. In case a
dependency hasn't arrived yet it'll make sure those are loaded before this.
