Show the generation

What we are doing

We write the counter in the strip above the grid: Generation 4.

```js
  ctx.fillStyle = 'white'
  ctx.font = 'bold 16px sans-serif'
  ctx.textAlign = 'left'
  ctx.fillText('Generation ' + generation, 8, 24)
}
```

What it means

• ctx.font picks the size and style, textAlign = 'left' puts the text's left end at x.
• fillText(text, x, y) paints the text; y is the line the letters sit on.
• 'Generation ' + generation joins a text and a number: 'Generation 4'.

Your turn

At the end of draw, after the loops and before its last }, leave an empty line and write the four lines.
