 | 'ng_no_private_call': 2                                      | All scope's properties/methods starting with $$ are used internally by AngularJS. You should not use them directly. |
 | 'ng_no_services': [2, ['$http', '$resource', 'Restangular']] | Some services should be used only in a specific AngularJS service (Ajax-based service for example), in order to follow the separation of concerns paradigm. The second parameter specifies the services. The third parameter can be a list of angular objects (controller, factory, etc.). Or second parameter can be an object, where keys are angular object names and value is a list of services (like {controller: ['$http'], factory: ['$q']}) |
