Tell us what’s happening:
I did not understand what is card? Is it array?

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 += 1;
break;
case 7:
case 8:
case 9:
count;
break;
case 10:
case 'J':
case 'Q':
case 'K':
case 'A':
count-=1;
break;
}

if(count>0){
return count + " Bet";
}
else{
return count + " Hold";
}
return "Change Me";
// 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');

Nope, look at the last line of given code.

cc(2); cc(3); cc(7); cc(‘K’); cc(‘A’);

It’s a single number of a letter.

Correction: It’s a single digit (0 - 9 ) or a character (a - z)

I think you need to delete that `return 'Change me'` because you are using the If statement. Also do you really need the case 7, case 8, and case9? Think about it
