I think I understand the createTokens method (though it is quite confusing) but I don't understand this line of code....
let token = new Token(i, this);
If I am correct, the 'i' is passed to the Token object so that the number can be used in the ID? But why is 'this' passed to it? What purpose does this serve?

It's been a while since I took that course, but if I remember correctly, passing this into the function passes the correct player object into the function, so that the tokens can be assigned to the correct person/player.
One way to get a better understanding is to log out this right before that function: console.log(this)
Seeing what object is printed to the console will take away some of the abstraction (which could be helpful).

11,608 PointsHey Brandon, just after posting, I looked back at the Token.js file, and you're absolutely right.
For a minute, I forgot where the properties were being passed to. Thanks!
