Basic JavaScript - Counting Cards

Tell us what’s happening:
I dont really understand why my code is not working. I do the same thing in c# and it works. Waht is the difference here.

Your code so far

let count = 0;

function cc(card) {
  // Only change code below this line
if(card === "J" || card === "Q" || card === "K" || card === "A" || card === 10){
  count--;
}
else if(card === 7 || card === 8 || card === 9)
{
//nothing happens
}
else if(card === 2 || card === 3 || card === 4 || card === 5 || card === 6)
{
count++;
}
else if(count > 0)
{
  return count + " Bet";
}
else if(count <= 0)
{
  return count + " Hold";
}


  
  // Only change code above this line
}

cc(2); cc(3); cc(7); cc('K'); cc('A');
var a = cc(2);
console.log(a);

Challenge: Basic JavaScript - Counting Cards

Link to the challenge:

try just logging this:
console.log(cc(2));
instead of

cc(2); cc(3); cc(7); cc('K'); cc('A');
var a = cc(2);
console.log(a);

You will see that your function returns undefined.
