AngularJS Tutorial 18- $rootScope
In this tutorial, we will learn what is $rootScope in AngularJS and how is it differ from $scope object
In our previous tutorials, we have already covered $scope object that acts like the bridge between your JS code (Controller) and view
In AngularJS each Controller has its own $scope object that is used to bind properties and methods to specific controller
On the other hand $rootScope works on the root level so $rootScope act like a global variable. You can have single $rootscope per application and the $scope of $rootscope is inherited in its own child scope.
All $scopes objects get inherited from $rootScope object.
To use $rootScope you need to inject $rootScope object inside a function run() method that you will create on module object
app.run(function($rootScope){
$rootScope.name="Angular Main App";
});
