Extending $q promises with a .set method

angularExtensions.js

angular.module("myApp")
.config(function ($provide) {

	$provide.decorator('$q', function($delegate) {
		var defer = $delegate.defer;
		$delegate.defer = function() {
			var deferred = defer();
			deferred.promise.set = function(object, property) {
				return deferred.promise.then(function(value) {
					object[property] = value;
					return value;
				});
			};
			return deferred;
		};
		return $delegate;
	});
	
});

app.js

angular.module("myApp").controller(function ($scope, myServiceApi) {

  // traditional way
  myServiceApi.getData().then(function (data) {
    $scope.data = data;
  });
  
  // simpler way
  myServiceApi.getData().set($scope, "data");

});

Pretty cool!
