Please, I don’t know what next to do on this challenge;

Your code so far


var count = 0;

function cc(card) {
  // Only change code below this line
  switch (card) {
    case 2:
    case 3:
    case 4:
    case 5:
    case 6:
    count++;
    break;
    case 10:
    case "J":
    case "Q":
    case "K":
    case "A":
    count--;
    break;
  }
  
  
  return count + " " + holdbet;

  var holdbet = "Hold";

  if (count > 0) {
    holdbet = "Bet";
  }
  // Only change code above this line
}

// Add/remove calls to test your function.
// Note: Only the last will display
cc(2); cc("K"); cc(10); cc('K'); cc('A');

A return statement stops the function and returns something, everything after it is not executed, as such holdbet is undefined
