A function for a new game

What we are doing

A new game means an empty sequence, no light, and a first round. We collect that in one function, reset, and the first game starts through it too.

```js
let sequence // the pads to repeat, growing by one every round

let lit // the pad lit right now, or -1
let litFor

function reset() {
  sequence = []
  lit = -1
  litFor = 0
  nextRound()
}

reset()
requestAnimationFrame(loop)
```

What it means

• sequence, lit and litFor are now only declared; reset gives them their values.
• reset ends with nextRound(), which adds the first pad and starts the show.
• reset() at the bottom replaces the old nextRound() call.

Your turn

1. Remove the values from let sequence, let lit and let litFor (keep the comments).
2. Under let litFor, leave an empty line and write reset.
3. At the very bottom, replace nextRound() with reset().
