What is $scope and $rootScope ?

$scope is a JavaScript object that refers to the application data

The $rootScope acts as a global variable. All the $scopes of an AngularJS application are children of the $rootscope.

1. Broadcast/Emit the data

 $rootScope.$broadcast('showIncidentDetails’, variable);
$rootScope.$emit('showIncidentDetails’, variable);

2.Receive the data

$rootScope.$on('showIncidentDetails', function(event,data) {
             $scope.showForm= data;
   });
