I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Note: Backticks are not single quotes.

1- are you sure this is your whole code? there seems to be stuff missing

2- what’s the challenge link?

3- what do the failing tests say?

3bis- do you understand why they are failing?

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 7:
  case 8:
  case 9:
 
  count --;
  break;

}
var holdbet = 'Hold';
if (count > 0){
  holdbet = 'bet'

}
return count + "" + holdbet;

  
  // 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');

below is the challenge
You will write a card counting function. It will receive a card parameter, which can be a number or a string, and increment or decrement the global count variable according to the card’s value (see table). The function will then return a string with the current count and the string Bet if the count is positive, or Hold if the count is zero or negative. The current count and the player’s decision ( Bet or Hold ) should be separated by a single space.

you did not answer any of my questions
even if now it seems your code is not missing anything
also please format your code as shown above

5- do you know what your function is returning? try using console.log()

what about cards 10, J, Q, K, A?

even after changing them it did not work but let me try again and see

11

the codes need to do:

2 : count = 1 [ 2, 3, 4, 5, 6 ] + 1
4 : count = 2 [ 2, 3, 4, 5, 6 ] + 1
8 : count = 2 [ 7, 8, 9 ] + 0
J : count = 1 [ 10, J, Q, K, A ] - 1
3 : count = 2
return value is…
count = 2 [positive number]

2 Bet

ok let me try and see
