angularjs $timeout without delay parameters reason

Question

In a few script I can find for instance

$timeout(function () {
    $scope.my = 1;            
});

instead of simply

$scope.my = 1;

What's the purpose to call $timeout without delay?

Answer 1

This is a hack. :) But usually the intention is to wait until the end of the $digest cycle and then set $scope.my to 1. Timeouts are called after all watches are done.
