Remember the best score

What we are doing

The best score is kept in localStorage, the browser's small notebook that survives closing the page. It is read when the page loads and saved when a game ends with a new record.

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

      state = 'over'
      if (score > best) {
        best = score
        localStorage.setItem('pinball-best', best)
      }

  ctx.font = '13px sans-serif'
  ctx.fillText('Best ' + best, 200, 50)
```

What it means

• localStorage.getItem(name) reads a saved value as text, or null if there is none. Number(...) makes it a number; || 0 uses 0 when that gives nothing useful.
• When the game ends with a higher score, setItem saves it under the same name.
• Best is written in the middle of the top, smaller than the rest.

Your turn

1. Under let flash write let best = ....
2. In update, inside the else block, under state = 'over', write the if block.
3. In draw, under ctx.textAlign = 'center', write the two Best lines.
