How does the output work?

I’ve solved the problem, but I do not understand how the code affects a sequence and the output

let count = 0;

function cc(card) {
// Only change code below this line
  case 1:
  case 2:
  case 3:
  case 4:
  case 5:
  case 6:
  count ++;

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

  return count + " Bet"
  return count + " Hold"

// Only change code above this line

cc(2); cc(1); cc(10); cc('K'); cc('A');

Then I don’t understand - how did you solve it?

Can you be more specific about what you don’t understand?

I got it now.

count is a global variable, and the cc function stores its output in count.
