Tell us what’s happening:

``````
var count = 0;
function cc(card) {
// Only change code below this line
if(card >= 2 && card <= 6){
count++;
return count + 'Bet';
}else if(card >= 7 && card <= 9){
count += 0;
return count + 'Hold';
}else if(card = 10 || 'J' || 'Q' || 'K' || 'A'){
count--;
return count + 'Hold';
}
if(card > 0){
return count + 'Bet';
}else{
return count + 'Hold';
}

return count;
// Only change code above this line
}

// Note: Only the last will display
cc(2); cc(3); cc(7); cc('K'); cc('A');
``````

`count++` in the following line, do the same thing as `count += 1`. Thank you @snowmonkey for correcting the mistake.

The problem in the following lines here is that you are assigning number 10 to `card`. In JS: `=` is used for assignment and `==` or `===` are used for comparison. I suppose you already know the difference between `==` and `===`. (If you have no idea, let me know.)

The second problem is that you are using the operator `||` but after that there’s no comparison, you should here try to compare card again with J, Q, K and A: …`|| card == 'J' || card == 'Q'`… etc.

Then the following code is going to be with no use, unless, you try to check whether `count > 0`, `count == 0` and `else` you output the right string.

Of course, if you do this then, you should take off the `return statements` in the `else ifs` of the previous code.

I hope this was useful,
and it’s up to you now to figure out how to fix these and come up with a better solution. (Let us know if you have anything new, I will be happy to help you further.)

So a small correction: `count +=1` and `count++` return the same value. The latter is referred to as a ‘post-fix increment operator’.

Thank you all. I solved the problem.

Good Luck & Happy Coding.
