Draw every frame

What we are doing

The field will change with every click, and later a clock will tick. A loop redraws it before every screen refresh.

```js
function loop() {
  draw()
  requestAnimationFrame(loop)
}

newGame()
requestAnimationFrame(loop)
```

What it means

• loop draws, then books itself for the next frame.
• The last line starts the loop, replacing the single draw() call.

Your turn

Above newGame() at the bottom, write loop. Replace the last draw() with requestAnimationFrame(loop).
