# Analysis of checking a draw in the tic-tac-toe game in JavaScript

Let's now consider a draw. Obviously, a draw occurs if all cells are filled and there is no winner. Let's do it:

`function start(cells) { let i = 0; for (let cell of cells) { cell.addEventListener('click', function step() { this.textContent = ['X', 'O'][i % 2]; this.removeEventListener('click', step); if (isVictory(cells)) { alert(this.textContent); } else if (i == 8) { alert('draw'); } i++; }); } }`
