While going through the youtube video of yours where you had used vanilla js and even in the course in scrimba there is a problem with the win condition for the pacman game.
If you change the deeply equals to a normal equal it'll do it.
Do look into this.

While playing the game I realised that some times the ghost suddenly becomes invisible and then it re-appears again after a ceratin interval of time. While the ghost remain disappeared the checkGameOver() function still works. This means that we cann't see the ghost but going into the same block in which he is results in game over.

I have the whole createboard() function created, as well as everything in the html file, and the css, but all I get is the score displayed.

how did you come up with the layout array
