I can't get the tic tac toe boxes to clear the board when a new game starts

So I have a tic tac toe game; when the player wins a win screen is displayed; on that screen is a new game button; when the user clicks that button, the board reappears, but the boxes are still filled in with the players moves -- I want the board to be clear so a new game can start. Here's my repo. Thanks!

You need to loop through the box elements to clear them.

I noticed at the beginning of newGame you have statements that appear to be intended to remove the box-filled classes from the box elements, but the collection (boxes) doesn't have a classList property itself. But if you use a loop which includes an index variable, and then use that variable to index into the collection, you can easily remove the classes from every individual box.

In jQuery, collections can be operated on with a single statement. If you've used jQuery before that may be the cause of the confusion.
