Light a pad for a while

What we are doing

A pad is lit for a number of frames. light(pad, frames) sets which pad is lit (lit) and for how long (litFor).

```js
let litFor = 0

function light(pad, frames) {
  lit = pad
  litFor = frames
}
```

What it means

• litFor counts how many frames the lit pad stays lit.
• light takes two parameters: the pad number and the number of frames.

Your turn

1. Under let lit, write let litFor = 0.
2. Above function draw, write light and an empty line.
