Example: Shuffle Deck of Cards

  "3",
  "4",
  "5",
  "6",
  "7",
  "8",
  "9",
  "10",
  "Jack",
  "Queen",
  "King",
];

// empty array to contain cards
let deck = [];

// create a deck of cards
for (let i = 0; i < suits.length; i++) {
    for (let x = 0; x < values.length; x++) {
        let card = { Value: values[x], Suit: suits[i] };

}

// shuffle the cards
for (let i = deck.length - 1; i > 0; i--) {

//output
