Counting Cards. Is this question written correctly?

I do not think this question is written properly. Is it giving an array for the args? I need to know what is coming in so I can structure the code properly.

var count = 0;

function cc(card) {
  // Only change code below this line
    case 1:
    case 2:
    case 3:
    case 4:
    case 5:
    case 6:
    case 10:
    case "J":
    case "Q":
    case "K":
    case "A":
  let val;
  if (count > 0){ return val = "Bet"}
  else {return val = "Hold"}
  return (count, val) ;
  // 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');

Link to the challenge:

The function receive one card, for that card you need to update the global count variable, and return a string based on the value of the count variable

It is written correctly. You need to remember what return does, this part doesn’t work:
