var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  
  $scope.$watch(function () { },
    function (newValue, oldValue, scope) { 
      
      scope.$apply(function () {
        
        console.log('This will not work');
      });
    }
  );
    
  $scope.$watch(function () { },
    function (newValue, oldValue, scope) { 
      
      scope.$applyAsync(function () {
        
        console.log('This will work as you are using $applyAsync!');
      });
    }
  );
});
