Basic Example for querying firestore collections duplicate variable

[raphrstuff]

The example here under Basic Example imports "query" but also declares a const query in the function body causing this example not to work.

It also gives an error:

Uncaught ReferenceError: Cannot access 'query' before initialization

If I move the query before the function it works, but then I am not able to give it where variables.
