[Firebase + Angular] How to handle objects with arrays

Hey there,

You are correct in saying that if you sync an object via $asObject(), even
deeply nested array-like object will be seen as key-value pairs instead.
This is probably something which is not going to change since the
complexity there is very high and will not be practical to make work. If
you want to accomplish your goal, you will have to sync categories via
$asArray() and the entire object via $asObject(), as you suggested.

In this simple example, you may just want to sync categories and then use
the $set() method on $firebase to update title. This will save you the
memory needed to load the entire object via $asObject() and gets rid of any
confusion from syncing categories to two different objects.
