my solution:

function shuffle(arr) {
    let j, x, i;
    for (i = arr.length - 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() {
const suites = ['♠︎','♣︎','♥︎','♦︎'];
const ranks = ['Ace','King','Queen','Jack','10','9','8','7','6','5','4', '3','2']
let deck = [];
for (i=0; i < suites.length; i++) {
    for (j=0; j < ranks.length; j++) {
        let card = [`${ranks[j]} ${suites[i]}`]
return deck;
let myDeck = createDeck();

for (i = 0; i < myDeck.length; i++) {

Do you think something is wrong here? Please tell me; thanks in advance.
