Angular dependency injection

gistfile1.js

angular.module('module')
    .factory('myService', function($scope, $http, otherService) {
      // ...
    });

// is the same as
angular.module('module')
    .factory('myService', ['$scope', '$http', 'otherService', function(scopy, ಠ_ಠ, $scope) {
      // scopy == Angular's $scope 
      // ಠ_ಠ == Angular's $http
      // most alarmingly, $scope == otherService, which is a downright dirty thing to do to the maintentnece team
    }]);

Now that I have done some learning this helps me a lot thank you.
