Does Firebase ref.removeAllObservers() also remove child observers recursively?

Question

I have seen a few questions about this but none of them really confirms my query.

If I .removeAllObservers() at a parent node, does this also recursively re

Answer 1

The API documentation for removeAllObservers() states:

Removes all observers at the current reference, but does not remove any observers at child references. removeAllObservers must be called again for each child reference where a listener was established to remove the observers.

This should be unambiguous.
