What is the difference between $scope and $rootScope in AngularJS?

In AngularJS, $scope and $rootScope both play essential roles in defining the structure of the application and managing data binding. Below are the key differences between $scope and $rootScope in AngularJS:

• $scope: $scope is an object that represents the application model and acts as a bridge between the controller and the view. Each controller in AngularJS has its own $scope, which helps in organizing and managing data specific to that controller's view. When a new controller is created, a new $scope object is also created, which inherits properties from its parent $scope. The $scope is used to store and access data within a specific controller or view.
• $rootScope: $rootScope is an object that represents the top-most scope in an AngularJS application. It is essentially the parent of all $scope objects and is accessible across the application. Values stored in $rootScope can be accessed by any controller or service within the application. While $rootScope can be powerful for sharing data between controllers and services, it is recommended to use it sparingly as it can lead to tightly coupled and less maintainable code.

Overall, $scope and $rootScope serve distinct purposes in AngularJS, with $scope being more localized and specific to individual controllers, while $rootScope provides a global scope accessible throughout the application.

Understanding the differences between $scope and $rootScope is crucial for developing well-structured and maintainable AngularJS applications.
