The game loop

What we are doing

A game loop runs again and again: update, draw, and ask the browser to run it again before the next screen refresh (requestAnimationFrame, about 60 times a second). The words start to fall.

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

reset()
requestAnimationFrame(loop)
```

What it means

• loop runs one turn: move the words, then draw them.
• requestAnimationFrame(loop) inside it books the next turn, so it keeps going.
• The last line starts the loop. It replaces the old single draw() call.

Your turn

At the bottom, write loop above reset() and replace draw() with requestAnimationFrame(loop).
