The "Token" object constructor uses a Player object as the second argument, not just the player's name.

Inside of the class Player, every time the keyword "this" is used, it is referencing Player, right? so even in let token = new Token(i, this), this = Player. I don't think this really helps me understand what is going on here but at least I can say this = Player. right? idk. I'm going to keep moving forward and hope this stuff starts to make some sense.

The keyword "this" would refer to the current instance of the class, not class "Player" itself.
