AngularJS : How to watch service variables?

Question

I have a service, say:

factory(\'aService\', [\'$rootScope\', \'$resource\', function ($rootScope, $resource) {
  var service = {
    foo: []
  };

  return

As far as I can tell, you dont have to do something as elaborate as that. You have already assigned foo from the service to your scope and since foo is an array ( and in turn an object it is assigned by reference! ). So, all that you need to do is something like this :

function FooCtrl($scope, aService) {                                                                                                                              
  $scope.foo = aService.foo;

 }

If some, other variable in this same Ctrl is dependant on foo changing then yes, you would need a watch to observe foo and make changes to that variable. But as long as it is a simple reference watching is unnecessary. Hope this helps.
