#Sometimes I want to munge data that I've pulled from a backend with Angular. The Promises implementation augments the object with it's own $properties and I don't want to munge those.

app = angular.module 'GetOffMyLawn'

app.controller 'DangKids', ($scope, $resource) ->
  Wat = $resource '/wat'
  Wat.get {}, (data) ->

    #data is something like { foo: {something: 1, somethingElse: 2} }

    for k, v of data

      #But we need to check for the $properties added by the Promises implementation.

      if k.charAt 0 is '$'
        console.log 'Get off my lawn!'
        continue

      #If that's fine, then munge the data

      v.computedValue = v.something * v.somethingElse
