A draw

What we are doing

If the board fills up and nobody has four, it is a draw. The board is full exactly when every cell of the top row is taken.

```js
} else if (board[0].every((cell) => cell !== 0)) {
  winner = 'draw'
} else {

if (winner === 'draw') message = 'Draw. Click to play again'
```

What it means

• else if checks a second condition only when the first was false.
• every is true when the test holds for every item: every cell of the top row is not 0.
• winner becomes the text 'draw', which counts as true, so the game stops.

Your turn

1. In land, between the win block and else, write the else if for a draw.
2. In draw, under the yellow line, write the draw message.
