Count the moves

What we are doing

A move is two cards turned over. We count moves in moves: zero in a new game, one more each time the second card of a turn is opened.

```js
let moves

  moves = 0

  if (opened.length < 2) return

  moves += 1
```

What it means

• moves starts at 0 in newGame.
• moves += 1 sits right after the "wait for the second card" line, so it counts once per pair of cards.

Your turn

1. Under let opened, write let moves.
2. In newGame, under opened = [], write moves = 0.
3. In flip, under the empty line after if (opened.length < 2) return, write moves += 1.
