$rootScope.$broadcast vs. $scope.$emit

Question

Now that the performance difference between $broadcast and $emit has been eliminated, is there any reason to prefer $scope.$emit to $rootScope.$broadcast?

They are different, yes.

$emit is restricted to the scope hierarchy (upwards) - this may be good if it fits your design, but it seems to be a rather arbitrary restriction.

$rootScope.$broadcast works across all that choose to listen to the event, which is a more sensible restriction in my mind.

Am I missing something?

Answer 1

Both are different $emit dispatches an event upwards through the scope hierarchy, while $broadcast dispatches an event downwards to all child scopes.
