my version of the createDec function, its better or worse?

const 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:
  //i loop through the suites array
  for(let k = 0; k < suites.length; k++) {
    //then i loop through the ranks array
    for(let l = 0; l < ranks.length; l++) {
      //then i declare an array called card and insert to the array the specified rank and suite of the iteration, the card contain for example a "card" like >> ['♥︎', 2]
      let card = [ranks[l],suites[k]];
      //finally after i inserted the rank and the suite i add the "card" to the deck array.
      deck.push(card);    
   }
 }
  shuffle(deck);
  return deck;
}
