Counting Cards ununderstood

Tell us what’s happening:

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;
      return "\"" + count*card + " Bet\"";
    case 7:
    case 8:
    case 9:
      return "\"" + 0 + " Hold\"";
    case 10:
    case 'J':
    case 'Q':
    case 'K':
    case 'A':
      count -= 1;
      return "\"" + count + " Bet\"";
  }
  
 
  // Only change code above this line
}

// Add/remove calls to test your function.
// Note: Only the last will display
cc('Q');

The returned string shouldn’t have literal double quotes in them. The example output have double quotes to tell you that the expected output are strings.

Your code is also returning early. It should add or subtract from count depending on the input, and after that you’ll determine if count is positive or negative.

still complain
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;
return count + " Bet";
case 7:
case 8:
case 9:

  return 0 + " Hold";
case 10:
case 'J':
case 'Q':
case 'K':
case 'A':
  count -= 1;
  return  count + " Hold";

}

// Only change code above this line
}

// Add/remove calls to test your function.
// Note: Only the last will display
cc(10);

You’re not supposed to return “Bet” if the count increases or “Hold” if the count decreases. You need to check if count is positive. If it is, return the “Bet” string. Otherwise return the “Hold” string.

Can you show me your code so far?

7 
var count = 0;

function cc(card) {
  // Only change code below this line
   
 if(card >= 2 && card <=6){
   count +=1;
   return count + " Bet";
 }
  else if(card >=7 && card <=9){
    return count + " Hold";
  }else if(card ==10 || card == 'Q' || card== 'J' || card == 'K' || card =='A'){
    count -=1;
    return count + " Hold";
  } // Only change code above this line
}

// Add/remove calls to test your function.
// Note: Only the last will display
cc(2);

Keep in mind what I said:

Your code is not doing any such checks at all.
