Counting Cards " 'J' is not defined" HELP!

JavaScript

Tell us what’s happening:
This code is failing the test with: " ‘J’ is undefined"
What am I missing?

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 7:
    case 8:
    case 9:
    count = count;
    break;
    case 10:
    case J:
    case Q:
    case K:
    case A:
    count --;
    break;
  }
  if (count <= 0){
    return count + "Hold";
  }
  else {
    return count + "Bet";
  }
  
  // Only change code above this line
}

// Add/remove calls to test your function.
// Note: Only the last will display
cc(2); cc(3); cc(7); cc('K'); cc('A');

sorry, the exact message is, " ‘J’ is not defined.", not “undefined”.

I am only getting this error with regards to J not having an issue with the other letters. When I add quotes, it fails all over the place.

    case 10:
    case "J":
    case "Q":
    case "K":
    case "A":
    count --;
    break;
