Broadcasts in controllers (Y031)

[sebastianhaas]

Hey! I'm having some trouble understanding the following sentence from Y031:

Consider using $scope in a controller only when needed. For example when publishing and subscribing events using $emit, $broadcast, or $on consider moving these uses to a factory and invoke from the controller.

While the Why? is perfectly clear to me, I'm somehow missing the answer to this very specific issue. How do I move a possible event registration, e.g. $scope.$on() to a factory? Can somebody provide some code for demonstration?

However I do understand that it is possible to avoid broadcasts at all with the use of factories. Is that the proposition of the above sentence?

I just realized that there is already an Issue opened on that topic #398 that I must have overlooked at first. I will move my question there.

Since there was no response in the other ticket I'll reopen this.

just closed this in #398

Thank you. I find that section much clearer now.
