Suggestion to rename Firestore doc() to ref()

[0x80]

This to me reads like a mistake:

getDoc(doc("some/path"))

The confusion comes from the fact that doc() doesn't return a document but a reference. With versions prior to 9, this wasn't much of an issue, but the functional style makes it look a bit funky.

I suggest renaming it to ref(), which would also make it consistent with the Firebase storage API. So:

getDoc(ref("some/path"))

Of course, collection also returns a ref, but that name doesn't create confusion for me. Maybe partially because you would not expect a synchronous call to collection() to return the actual documents. So this looks fine I think:

getDocs(collection("some"))
getDocs(query(collection("some"), limit(10))
