Does findExitTo work with room names?

If not, how would a creep get the id of the spawn that's in their room?

[SystemParadox]

According to https://docs.screeps.com/api/#Room.findExitTo, findExitTo can accept either a string (room name) or a Room object.

I don't know why you need the spawn ID for this, but you can get spawns like this:

let spawn = room.find(FIND_MY_SPAWNS)[0];
