Your best

What we are doing

The fewest shots you ever needed to clear the table is your best. It is kept in localStorage, which the browser keeps even after the page is closed, and shown at the top right.

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

    if (best === 0 || shots < best) {
      best = shots
      localStorage.setItem('pool-best', best)
    }

  ctx.textAlign = 'right'
  ctx.fillText('Best ' + (best || '-'), RIGHT, 22)
```

What it means

• localStorage.getItem reads a saved text (or null); Number(...) makes it a number; || 0 uses 0 when there is none.
• On a win, the shots are saved if there is no best yet or they are fewer.
• best || '-' shows the number, or - while it is 0.

Your turn

1. Under let state ... write let best = ....
2. In update, under state = 'won', write the if block.
3. In draw, under the Shots text line, write the two Best lines.
