I am having trouble with the shuffle the deck challenge, I've been working on it for quite some time.

function createDeck() {
  deck = []
  var suites = ['♠︎','♣︎','♥︎','♦︎'];
  var ranks = ['Ace','King','Queen','Jack','10','9','8','7','6','5','4', '3','2'];
  // add your code below here:
  for (var i = 0; i < suites.length; i += 1){
       for (var j = 0; j < ranks.length; j += 1){
         var card = [ranks[j],suites[i]];
         deck += card;
         /*console.log(card); The output of this line is what I want          my array to look like 
         */
       }
    } return shuffle(deck);
      console.log(shuffle(deck));
      console.log(deck);
}
createDeck();

One way to solve this is to use the push method to add the result of your inner and outer loop to the deck array:

for(var i = 0; i < suites.length; i++){
      for(var j = 0; j < ranks.length; j++){
          deck.push([ranks[j], suites[i]]);
      }
  }

So within the inner loop, you are taking the rank and suite and putting them within an array, and then adding them to the main deck array. Then you can create a new deck that takes the results of the function you just created and print them out with another for loop:

var myDeck = createDeck();
for(i = 0; i < myDeck.length; i++){
 console.log(myDeck[i].join(' of '));

There may be a better way to do this, but this is what I did to complete the challenge.
