Could I use the for...in loop in createDeck()?

function createDeck() {
  var suites = ['♠︎','♣︎','♥︎','♦︎'];
  var ranks = ['Ace','King','Queen','Jack','10','9','8','7','6','5','4', '3','2'];
  var deck = [];
  // add your code below here:
  for (let suit in suites) {
     for (let rank in ranks) {
        let card = [suit, rank];
      deck.push(card);
    }
  }
  shuffle(deck);
  return(deck);
}

function createDeck() {
  var suites = ['♠︎','♣︎','♥︎','♦︎'];
  var ranks = ['Ace','King','Queen','Jack','10','9','8','7','6','5','4', '3','2'];
  var deck = [];
  // add your code below here:
  for (var i = 0; i < suites.length; i++) {
    for (var y = 0; y < ranks.length; y++) {
      let card = [ranks[y], suites[i]];
      deck.push(card);
    }
  }
  shuffle(deck);
  return(deck);
}

// 6. Call the createDeck() function and store the results in a new variable named myDeck
var myDeck = createDeck();
//* 7. Use a for loop to loop through the deck and list each card in the order the appear in the newly shuffled array. Use the log() method to print out a message like this, once for each card:
//"7 of ♥.︎"
*//
console.log(myDeck)
for (var i = 0; i < myDeck.length; i++) {
  console.log(myDeck[i][0] + " of " + myDeck[i][1])
}
