Hi Ben,
Consulting the source provides you with the ultimate answers. 1. They are executed on the spot. here you can find <https://github.com/angular/angular.js/blob/master/src/ng/rootScope.js#L1080> the exact details 2. Wrong, only those that are used in a 2-way binding, or manually watched upon. 3. No, well, not entirely. Arrays and Objects are passed by reference, so those are not copies, rather than direct references. other primitives are indeed copied. 4. $scope.$watch("array.length", function (l) {console.log('new length:',l)}). There are other way’s, but this one is IMHO the most straightforward. Regards Sander -- You received this message because you are subscribed to the Google Groups "AngularJS" group.
