which is best to use $rootScope.$emit or $$rootScope.$broadcast for angularjs loader indicator in angularjs

Question

$rootScope.$emit flows up to $rootScope and $rootScope.$broadcast flows down the scope to $rootScope and all $scope's in angularjs. I am still confused of what exactly to use for angularjs loader indicator .

Answer 1

$rootScope.$emit only lets other $rootScope listeners catch it. This is good when you don't want every $scope to get it.

$rootScope.$broadcast is a method that lets pretty much everything hear it.
