Your shot

What we are doing

playerShoots(r, c) fires at the enemy's fleet, unless you already tried that square: shooting twice at the same square would waste a shot.

```js
function playerShoots(r, c) {
  if (myShots[r][c]) return
  fire(enemyFleet, myShots, r, c)
}
```

What it means

• null counts as false, 'miss' and 'hit' as true: a square already tried makes return leave at once.
• Otherwise it fires at enemyFleet and records the result in myShots.

Your turn

Write playerShoots above function drawSea(, followed by an empty line.
