What distinguishes a root $scope from a child $scope?

  • Root $scope is global, while child $scope is local to a controller
  • Root $scope is read-only, while child $scope is mutable
  • Root $scope is used for data binding, while child $scope is for event handling
  • Root $scope is used for server-side communication, while child $scope is for client-side
A root $scope in AngularJS is global and is typically associated with the entire application. It can be accessed by all controllers and directives. On the other hand, a child $scope is local to a specific controller and inherits from the root $scope. Changes made to the child $scope do not affect the root $scope. Understanding the distinction between root and child scopes is important for managing data scope in AngularJS applications.
