Answer Posted / swati maheshwari
$apply handle exceptions.
scope.$digest() will only fire watchers on current scope, scope.$apply will evaluate passed function and run $rootScope.$digest().
First one is faster, as needs to evaluate watchers for current scope, second one is slower (needs to evaluate watchers for$rootScope and all it's child scopes).
When error occurs in one of the watchers and you use scope.$digest, it's not handled via $exceptionHandler service, so you need to handle exception yourself. scope.$apply uses try catch block internally and passes all exceptions to $exceptionHandler.
