Is there a way to subscribe to events on multiple objects using $watch

Starting from AngularJS 1.3 there’s a new method called $watchGroup for observing a set of expressions.

$ = 'foo';
$ = 'bar';

$scope.$watchGroup(['foo', 'bar'], function(newValues, oldValues, scope) {
  // newValues array contains the current values of the watch expressions
  // with the indexes matching those of the watchExpression array
  // i.e.
  // newValues[0] -> $ 
  // and 
  // newValues[1] -> $
