Gadgets are available on request but ResourceLoader is HUGE for Js devs. It deprecates almost everything- globals have to be now used through mw.config.get(' ');, addOnloadHook is deprecated, importScriptURI is deprecated and so much more. This is to move everything into an object oriented place, according to MW devs. Also, MW is making jQuery a reccomendation for everything- ajax, and even regular scripts. Now its $(function, not just function. A good thing though is that now its so much easier to load jquery ui as a dependency- i think it goes like mw.using('jquery.ui.dialog', function {// code }); for using jquery UI's dialog. By the time wikia updates mediawiki again, pretty much all your scripts will be broken unless you conform to the new standards...
