angular.js - $scope scope issue in AngularJS Controller

Question

controllers.controller('ctrl', ['$scope', function($scope) {
  console.log($scope);//
  $scope.add = function() {
    console.log($scope);//
  };
}]);

Why are the outputs of the above two scopes unequal?

Answer 1

Both outputs point to the $scope bound to the controller. The first one is executed when the controller is loaded, and the second one is executed when the add method is called. The execution time and status of the two are different.

Answer 2

It is the same object in itself, and the execution content may be different at different times
