Most programming languages have a full documentation or at least a complete list of all functions and classes and a short description, I noticed a few things in aura and apex that I can't find it's documentation page.
// in aura / controller.js:
$A
$A.get(e.force:closeQuickAction') // where is 'e.force:closeQuickAction' defined?
$A.get('e.force:showToast') // what are these!
$A.util
doInit: function (component, event, helper) {} // the js side component class documents?
// in visualforce .page files:
$Lightning
$Lightning.use
$Lightning.createComponent
I'm just looking for documentations about these, and I've already tried googling these, and it just won't take me to the source!
