Hi there,  
I am trying to create this function which will do the counting cards for Blackjack!  
The criteria is:

‘count’ variable will be incremented if ‘card’ is between 2 and 6;  
‘count’ will be incremented to 0 if ‘card’ is between 7 and 9; (nothing happens to count);  
‘count’ will be decremented if ‘card’ is 10, J, Q, K, A.

Here is the code:

```auto
let count = 0;

function cc(card) {
  if (card <= 6) 
    count++;
  else if (card >="10")
    count--;
  return count + (count > 0 ? ' Bet' : ' Hold');
}

const result = cc(2); cc(3); cc(4); cc(2); cc(2);
console.log(result);

```

Since my count was initialized to 0, should it return 4? Because all the numbers passed to card as a value was between 2 and 6;

No, it should return 5 but you made mistake when you assigned the result into function’s value.

```auto
const result = cc(2); cc(3); cc(4); cc(2); cc(2);
// this looks like 

const result = cc(2); 
cc(3); 
cc(4); 
cc(2); 
cc(2);
// therefore result is equal to 1. but if you write 
 cc(2); 
cc(3);
 cc(4);
 cc(2); 

const result = cc(2);
// then the result variable is equal to 5

```
