Stuck at a challenge i solved right, any help, i just need to pass

Tell us what’s happening:
Describe your issue in detail here.

  **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++;
    break;
  case 10:
  case 'J':
  case 'Q':
  case 'K':
  case 'A':
    count--;
    break;
/*case 7:
  case 8:
  case 9:
    count+=0
    break;*/
}
var holdbet ='Hold';
if(count>0 ){
  holdbet ='Bet';
}
// Only change code above this line
return count+''+holdbet;
}

cc(2); cc(3); cc(7); cc('K'); cc('A');

now I checked the video help, and he made almost the same code I made, then I copied his exact code and used it but I still didn’t pass. why?
thank you.

Put console.log(count+''+holdbet) in there before the return - it should help you understand what the problem is.

works perfectly, it add and subtract 1 when it needs , i check the cards called by the function, it all look right. how ever i found another solution on the forum help and it got me to pass.
but when i used the code that the help video provided, it didn’t pass even if it looks right and give right results on my visual studio.

@zak

''

If you changed your code, you should share it.

I also think that you have a problem with the string you are returning. '' is an empty string. ' ' is something different.

[zak]

that space in between single quotes has solved it thank you.
as of my previous code, here is it:

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++;
    break;
  case 10:
  case 'J':
  case 'Q':
  case 'K':
  case 'A':
    count--;
    break;
/*case 7:
  case 8:
  case 9:
    count+=0
    break;*/
}
if(count>0){
return count +' Bet';
} else{
return count + ' Hold';
}

// Only change code above this line

}

cc(2); cc(3); cc(7); cc('K'); cc('A');

this has passed the challenge.
it looked little wrong to me specially at the 8th line : card >= ‘A’ && card <= ‘Q’ because the strings Q and A are not number to compare them with < or >, but this still has passed. read below:

var count = 0;
function cc(card) {
  // Only change code below this line
    if (card>1 && card<7){
    count++;
    }else if (card>7 && card<10){
      count=count+0;
    } else if (card == 10 || (card >= 'A' && card <= 'Q')){
      count--;
    }
    if (count > 0){
    return count + " Bet";
    } else {
    return count + " Hold";
    }
}
// Add/remove calls to test your function.
// Note: Only the last will display
cc(2); cc(2); cc(10); cc(0); cc(0);
//console.log(cc('J'));

[JeremyLT]

I’m not a big fan of this solution. What is happening is that card, A, and Q are being converted to their ASCII code values. A has the ASCII value of 65 and Q has the ASCII value of 81.

As written, this code will respond to a lot of invalid values, while the switch version uses strict equality and will not change count based on invalid inputs.

[zak]

sounds right. thank you.
