Objects

!SLIDE bullets incremental

Modules (Mixins in Batman jargon)

  • Observable (gives get, set, observe)
  • EventEmitter (gives fire, prevent, allow)
  • Enumerable (gives filter, reduce given forEach)

!SLIDE bullets incremental

Pretty much everything in the Batman world descends from Batman.Object

class Batman.Object
  $mixin @::, Batman.Observable
  $mixin @::, Batman.EventEmitter
  • The @:: means "this class' prototype"

  • Batman.Object
  • Batman.Set
  • Batman.SetSort and Batman.SetIndex
  • Batman.Hash

SomeClass.observe 'awesomeness', (x) ->
  console.log x

SomeClass.set 'awesomeness', 10
# => "10" logged to the console
