Little improvements

[Israel Antonio Rosales Laguan]

• Cell HTML markup too large
  

  Tic-Tac-Toe/js/custom.js

  Line 30 in 1b8003c

   const htmlCeil = `<div class='board-cell cursor-pointer' onclick="game.move(this)" id="${x},${y}"> ${boardArray[x][y]}</div>`; 

• What about move all the "erase" logic into board.initialize()?
  

  Tic-Tac-Toe/js/custom.js

  Lines 38 to 39 in 1b8003c

   boardArrayDiv.innerHTML = ''; 
   winnerDiv.innerHTML = ''; 

• There is a typo, should be selectedRowColumnArray
  

  Tic-Tac-Toe/js/custom.js

  Line 76 in 1b8003c

   const selectedRowColumeArray = selectedCell.id.split(',');
