Uchambuzi wa Uthibitisho wa Draw katika Mchezo wa Tic-Tac-Toe kwenye JavaScript

Wacha sasa tuzingatie usawa. Ni wazi, kuwa usawa hufikia wakati seli zote zimejazwa na hakuna mshindi. Wacha tufanye hivi:

javascriptfunction 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++;
    });
  }
}
