Questions tagged [rootscope]

Every AngularJS application has a single root scope. All other scopes are descendant scopes of the root scope. Scopes provide separation between the model and the view, via a mechanism for watching the model for changes. They also provide an event emission/broadcast and subscription facility.

Every part of an AngularJS application has a scope. At the ng-app level, this scope is called the $rootScope. When Angular starts to run and generate the view, it creates a binding from the root ng-app element to the $rootScope. This $rootScope is the eventual parent of all $scope objects. So we can say that the $rootScope object is the closest object we have to the global context in an Angular app.

$rootScope is deprecated. Using it will make migration to Angular 2+ more difficult.
