angularJS $on event handler trigger order

Question

I was wondering two things, in the context of angularJS event handling.

1. How is defined the order in which handlers listening to the same event are triggered?

Answer 1

To add another comment on point #2, if you need to guarantee order you could implement an observer pattern using a service with an array of listeners. In the service you can define "addListener" functions that also defines how the listeners are ordered. You can then inject this service into whatever other components need to fire events.
