A $scope is a JavaScript object. The $scope working between the DOM elements and controller both.  The main role of $scope is to ties the DOM elements that is view to controller.     For Example, Just like MVC [Model-View-Controller], The model work between the view and controller and the Model ties the DOM element/view to controller. The AngularJs code for $scope with ng-controller var app = angular.module( "myApp" , []);   app.controller( "MyController" , [ '$scope' , '$http' , function (key, val) {      console.log(key);      console.log(val); }]);   app.directive( "myDirective" , function ($http, $parse) {      return {          link: function ($scope, scope, attrs) {              alert($scope);          }      } }); ...
