I just finished my Tic-Tac-Toe project and you can check it on this link on CodePen.
It took me some time to build this. This is by far the most challenging task to do for me.
I’ve noticed on similar topics many advice to do this project without implementing minimax algorithm. I strongly recommend to do it with Minimax, it’s gonna be little harder, but believe me it is worth. In my case, it changed everything, the way how I managed projects before, the way I’ve was implementing logic and so…
Please check and comment
