A deck

What we are doing

A deck has one card of every rank in every suit: 4 × 13 = 52. Two loops, one inside the other, make them all.

```js
let deck

function newDeck() {
  deck = []
  for (const suit of SUITS) for (const rank of RANKS) deck.push(card(rank, suit))
}

newDeck()
```

What it means

• deck = [] starts empty, so calling newDeck again gives a fresh deck, not a double one.
• For each suit, the inner loop goes through all 13 ranks.

Your turn

1. Under SUITS, write let deck (with an empty line before and after it).
2. Under card, write newDeck.
3. At the bottom, call newDeck() above draw().
