Basic JavaScript - Counting Cards Code Error

JavaScript
1

Tell us what’s happening:
Hi, can someone help me to identify why my code is still not working? I’m getting the error messages listed below:

  • Cards Sequence 10, J, Q, K, A should return the string -5 Hold
  • Cards Sequence 3, 2, A, 10, K should return the string -1 Hold

Thanks!!!

Your code so far

let 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 7:
  case 8:
  case 9:
    count += 0;
    break;
  case 10:
  case 'J':
  case 'Q':
  case 'k':
  case 'A':
     count --;
     break;
} 
  if (count > 0) {
       return count + " Bet";
    } else {
      return count + " Hold";
    }


  return "Change Me";
  // Only change code above this line
}

cc(2); cc(3); cc(7); cc('K'); cc('A');

I updated the code, but I still have the error message:
Cards Sequence 10, J, Q, K, A should return the string -5 Hold
Cards Sequence 3, 2, A, 10, K should return the string -1 Hold

let 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;
} 
  if (count > 0) {
       return count + " Bet";
    } else {
      return count + " Hold";
    }


  // Only change code above this line
}

cc(2); cc(3); cc(7); cc('K'); cc('A');

Let’s apply some formatting for readability

let 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": // Is this a valid card?
    case "A":
      count--;
      break;
  } 
  if (count > 0) {
    return count + " Bet";
  } else {
    return count + " Hold";
  }
  // Only change code above this line
}
