Card Counting Function

var count = 0;
function cc(card) {
  if (card <= 6){
    count++;
  }
  else if (card >= 10){
    count--;
  }
  else {
    count += 0;
  } 
  return count;
}

cc(2); 
cc("K"); 
cc(7); 
cc('K'); 
cc('A');

Writing a card counting function in JavaScript. If count <= 0 is should return count + " Hold". If count > 0 it should return count + " Bet". My issue is where do place the return so the function prints these outputs without returning and exiting the function.

This is how I solved it on FCC.

    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 = count;       
       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
}

// Add/remove calls to test your function.
// Note: Only the last will display
cc(2); cc("J"); cc(9); cc(2); cc(7);

This is my solution, you can use the ternary operator in the return:)

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;
      
  }
  
  
  return  count>0?count + " Bet":count + " Hold";
  // 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');

My answer:

LowValueCards = [2,3,4,5,6];
NoValueCards = [7,8,9];
HighValueCards = [10,"J","Q","K","A"];

if (LowValueCards.includes(card)) 
{
   count += 1;
} 
else if (NoValueCards.includes(card)) 
{
   count += 0;
}
else if (HighValueCards.includes(card))
{
   count -=1;
} 

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

I've just add the 0 case:

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 += 0;
  break;
case 10:
case "J":
case "Q":
case "K":
case "A":
  count--;
  break;
}
if (count > 0){
return count + " Bet";
}else if (count<=0) {
return count + " Hold";
}
}

use the switch

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 10:
    case "J":
    case "Q":
    case "K":
    case "A":
      count--;
      break;
  }

  if (count > 0) {
    return count + " Bet";
  } else {
    return count + " Hold";
  }
  //return "Change Me";
  // 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');

You're nearly there. You simply need to add in the return statements in an if...else... at the end of the function so it will display the result after all the cards have been counted. Also for the cards to be counted correctly(blackjack rules), you have to change the else...if... condition to else if (card <= 9) for String("K") to be counted as -1, like so:

var count = 0;

function cc(card) {
if (card <= 6) {
  count++;
} else if (card <= 9) {
  count += 0;
} else {
  count--;
}
if (count <= 0){
  return count + " Hold"; /* Return here */
} else {
  return count + " Bet";  /* and here */
}

}

cc(2); cc(3); cc(7); cc('K'); cc('A');

you can place the returns inside the if statements such as:

if (card <=6) {
count++;
return count + " Bet";
} 
else if (card >= 10) {
count--;
return count + " Hold;
}

I'm still only learning, but I encountered this problem in FCC and this is how i solved it.

Create another if statement like this to return the count you want:

if (count <= 0) {
    console.log(count + " Hold");
    //or window.alert("Same text here");
}
else {
    console.log(return count + " Bet");
    //or window.alert("Same text here");
}
