Tell us what’s happening:

Can someone help explain why the above code didn’t pass and the following code did? What went wrong?

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=0;
break;
case 10:
case 'J':
case 'Q':
case 'K':
case 'A':
count-=1;
break;
}
return count+""+(count>0?"Bet":"Hold");
/*
if (card >= 2 && card <= 6) {
count++;
} else if (card >= 7 && card <= 9) {
count += 0;
} else {
count--;
}
if (count <= 0) {
return count + " Hold";
} else {
return count + " Bet";
}
*/
// 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');

`return count+""+(count>0?"Bet":"Hold");`

You need a space between your count and string.
