Every fruit twice

What we are doing

Under the cards there are 8 fruits, each twice. SYMBOLS lists the 8 fruits, and newGame builds the 16 cards by putting the list twice into one array.

```js
const SYMBOLS = ['🍎', '🍌', '🍇', '🍒', '🥝', '🍋', '🍉', '🍑']

let cards

function newGame() {
  cards = [...SYMBOLS, ...SYMBOLS]
}

newGame()
```

What it means

• [ ... ] is an array: a list in order. Emoji are text, so they are in quotes.
• ...SYMBOLS spreads the list's items into the new array; twice gives 16 items.
• function newGame() { ... } defines the recipe; newGame() at the bottom runs it.

Your turn

1. Under TOP, write SYMBOLS, then let cards and newGame with empty lines between them.
2. At the very end, leave an empty line and write newGame().
