getListings() is still synchronous. You should make it async and return a promise. I could do this for you... but it is a better learning opportunity if you try it. If you want, you can also use Plunkr to do create a live version: http://plnkr.co

On it! Id rather go that route as well. Only other thing if you don't mind... is there a reason why I can't get $logs out of my app?

I don't remember this at all... hahahaha
