Set an async value in AngularJS

gistfile1.js

// imagine a factory with the following code somewhere in the factory:
app.factory('asyncFactory', function($q, $timeout) {
  // a factory always needs to return a value
  return {
    getAsyncValue: function () {
      var deferred = $q.defer();
      $timeout(function () {
          deferred.resolve('This is an item');
      }, 2000);
      return deferred.promise;
    }
  }
});

// now inside some controller we want to consume this factory:
$scope.description = simpleFactory.getAsyncValue();
$scope.description.then(function (result) {
	$scope.description = result;
});
