Count the shots

What we are doing

The goal will be to clear the table in as few shots as possible, so we count them and show the count above the table.

```js
let shots

  shots = 0

  shots += 1

  ctx.fillStyle = 'white'
  ctx.font = 'bold 16px sans-serif'
  ctx.textAlign = 'left'
  ctx.fillText('Shots ' + shots, LEFT, 22)
```

What it means

• shots is 0 after reset and goes up by one in shoot, only when a shot really happens.
• The text is drawn last, above the table on the left.

Your turn

1. Under let power write let shots; in reset, under power = 8, write shots = 0.
2. In shoot, write shots += 1 above state = 'rolling'.
3. At the end of draw, after the ball loop, leave an empty line and write the four text lines.
