I’m currently doing this part of the javaScript course and third or last test does not work please help me.

what’s your code? what have you tried?

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:

  break;

  case 10:

 case 'J':

 case 'Q':

 case 'k':

 case 'A':

 count--;

 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');

the card is K, not k
