Help w/ Counting Cards challenge

JavaScript
1

Tell us what’s happening:

I am completely stuck at this challenge and don’t know how the function sequences work.
Pleeeeeeese help.

Your code so far

js

var count = 0;

function cc(card) {
  // Only change code below this line
  if(card === 2&&card === 3&&card === 4&& card === 5 &&card === 6){
return "5 Bet";
  }
  
  // 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');

It seems you are approaching this from the wrong angle

You are trying to see if the card variables is 5 different things at once, but that will never be possible

You need to check the value of card and based on that you need to change (or not change) the global count variable, and then based on the count variable your function should return the current value of count with “Hold” or “Bet”

You are just trying to pass the tests, which will not really work easily because of how they are set up, the easiest thing is to just follow challenge instructions

The function sequence will change the global variable count based on each card passed in, and the last function will return the thing that matter for that case

I don’t completely understand what you are saying, I tried what I do, and I am still stuck. :frowning:

First thing first, try to change the value of variable count based on the value of card following the challenge instructions - as only one card is passed in you just need to do that. This will be your first step.
Once you have done that the other step is easier

You can do this in various ways, you just need a way to execute a piece of code if a condition is satisfied

it still didn’t work, but I got some code that I 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 = card + 1;
    break;
    case 7:
    case 8:
    case 9:
    count = card;
    break;
    case 10:
    case 'J':
    case 'Q':
    case 'A':
    case 'K':
    count = card-1;
    break;
  }
  if(count > 1){
  return count + "Bet";
}
if(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); cc(3); cc(7); cc('K'); cc('A');

It didn’t work but you are on the right way

First thing, if you change the value of count you need to do it using the previous value of count

If count is 0, and card is 10, you need to lower count by one and make it -1, your code instead do count = card - 1 so that would be 9

Fix that and you are a step closer

Second thing, you have condition for count > 1 and count < 1 but you are not doing anything for when count is 1

Third thing, you are returning strings like 0Hold, 1Bet - you are missing a space

Please read carefully the notice there’s only increments or decrements so you shouldn’t have something like count = card + 1; or count = card;

Also the the if test should with 0 (if positive)

and finally add space to the string in return statement
