Token only drops one space left right moves OK. checkForWin is not a function error after dropping a token. Thanks for any help.

The message is accurate, there is no "checkForWin" function in Game.js.

But there seems to be one in Space.js, was it added to the wrong file?

checkForWin() is function in Space.js and checkForWin is called in Game.js line 80. The devtools are saying in updateGameState the function checkForWin is not a function.

But the code in Game.js calls this.checkForWin(). The "this" means "in this same class", which means "Game" and it's not there!

Thanks, should be in Game.js checkForWin that is. But not sure why my token doesn't fall to bottom open space. It only drops one space. Also getting maximum call stack exceeded in space.js get owner method.

In Game.js on line 79, "mark" is being passed the target instead of the token. See if you can continue the debugging from there (hint: "player" is not an array).

If your original question has been answered, any additional issues should get a fresh question.
