A high score

What we are doing

The best score is saved in the browser's localStorage when a game ends, so it survives a page reload, and it is shown next to the score.

```js
let best = Number(localStorage.getItem('missile-best')) || 0

    if (score > best) {
      best = score
      localStorage.setItem('missile-best', best)
    }

  ctx.fillText('Score ' + score + '  Best ' + best, 10, 22)
```

What it means

• localStorage.getItem reads the saved text (or null); Number turns it into a number; || 0 covers the first game.
• When the game ends with a higher score, best is updated and saved with setItem.

Your turn

1. Under let pause write the best line.
2. In update, in the lost-cities block, write the if (score > best) block between state = 'over' and return.
3. In draw, add + ' Best ' + best to the score text.
