Basic JavaScript: Counting Cards Challenge


I’ve been trying to finish this challenge and all requirements are passed except this one:

Cards Sequence 2, J, 9, 2, 7 should return 1 Bet

My code:

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;
case 7:
case 8:
case 9:
count = 0;
case 10:
case “J”:
case “Q”:
case “K”:
case “A”:
count -= 1;
if (count > 0) {
return count + " Bet";
} else {
return count + " Hold";

// Only change code above this line


Can someone help me or give me a hint as to why that only requirement is missing?
A similar one, Cards Sequence 2, 2, 10 should return 1 Bet is passed and the outcome is the same = 1 Bet.

Thank you in advanced,

Look at what you are doing for cases 7,8, and 9. You are resetting the variable ‘count’ to 0. It’s probably better if you don’t do anything for those cases :slight_smile:


Oh my…

Thanks a lot. That was indeed helpful and enough so i could finish it and passed all requirements.

I just changed it to count += 0; and it worked. I was saying that if 7, 8, 9 then count = 0 and that was reseting the var count back to 0, ignoring the previous + 1. Thank you so much @shimphillip

But like @shimphillip mentioned, you really do not need any of the above code. Anytime you can reduce code without affecting readability, definitely remove the code.

What do you mean @RandellDawson?
What would be a better option?

Delete those 5 lines of code. The solution will work without them.

Thanks @RandellDawson, now i understood what you meant.

I thought that, for the purpose of the challenge it was required to put them in.
