Is return this.unusedTokens.shift() the same as return this.unusedTokens[0]?

I was wondering is there any difference between the Is return this.unusedTokens.shift() and this.unusedTokens[0]?

Both of those expressions will return the first token, but when you use "shift" it removes it from the array.

That's what I thought but if I log game.activePlayer.unusedTokens to the console before and after the shift expression it is the same. Why is that?

Perhaps "this" is something other than "game.activePlayer", and you're looking at the wrong list.

If you still have trouble, make a snapshot of your workspace and post the link to it here.
