while loop

while (currentCard !='spade'){
  currentCard = cards[Math.floor(Math.random() * 4)];  //Math.floor(Math.random() * 4) will give us a random number from 0 to 3. We’ll use this number to index the cards array, and assign the value of currentCard to a random element from that array.
  console.log(currentCard); //hence the currentCard array will have different elements each time you run based on the cards array
