can someone please show me where the suit is stored in the second position of the nested array? (8:23)

In the video Dave mentions how 'the suit is in the second position of the nested array'. I am unsure of where to see this in the code. Can someone please help me locate this? Thanks!

Watch the video @ 4:14 for this line:

card.push(ranks[j],  suites[i]);

You can also see the suites in the second position in the video's workspace in example_2d_array.js

Working Solution:

function shuffle(arr) {
  var j, x, i;
  for (i = arr.legnth - 1; i > 0; i--) {
    j = Math.floor(Math.random() * (i + 1));
    x = arr[i];
    arr[i] = arr[j];
    arr[j] = x;
  }
  return arr;
}


function createDeck() {
  var suites = ['spades', 'clubs', 'hearts', 'diamonds'];
  var ranks = ['Ace', 'King', 'Queen', 'Jack', '10', '9', '8', '7', '6', '5', '4', '3', '2'];
  var deck = [];

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

for (let i=0; i<myDeck.length; i++) {
  console.log(myDeck[i]);
}
