Build a Card Counting Assistant - Lab says pass, console says otherwise for certain tests

JavaScript

Tell us what’s happening:

The lab environment accepts my code as a solution and says it passes all tests, but according to the console, it doesn’t pass all of them.

Here are the tests the solution does NOT pass:

  • After the cards 2, 3, 4, 5, then calling cc(6) should return the string 5 Bet. (Output is: 1 Bet)

  • After the cards 10, “J”, “Q”, “K”, then calling cc(“A”) should return the string -5 Hold. (Output is: -1 Hold)

  • After the cards 2, “J”, 9, 2, then calling cc(7) should return the string 1 Bet. (Output is: 0 Hold)

  • After the cards 2, 2, then calling cc(10) should return the string 1 Bet. (Output is: -1 Hold)

I’m not completely satisfied here. Sure, I gave a “passable solution”, but the code technically still doesn’t work. Is there an extra string I need to return? Some math that I’m missing? Not sure which direction to take to make the solution complete.

I appreciate the help in advance. Cheers.

Your code so far

let count = 0

function cc (card) {
  if (card >= 2 && card <= 6) {
    ++count;
  } else if (card >=7 && card <=9) {
    count;
  } else if (card === 10 || card === "J" || card === "Q" || card === "K" || card === "A") {
   --count; 
  }

  if (count > 0) {
    return `${count} Bet`
  } else if (count <= 0) {
    return `${count} Hold`
  }
}

let valueDecision = cc()
console.log(valueDecision)

You need to handle the previous cards, too. Look at the tests. Plus, your call to cc is not passing in an argument.

As far as “handling the previous cards”, I would have to pass those in some kind of sequence. So perhaps there’s a variable that can be changed to accept a value that is a sequence of cards?

For my call, I left it blank so that I could pass arguments for testing at my leisure.

You can just do it like this:

cc(2)
cc(3)
cc(4)
cc(5)
console.log(cc(6))

or you could create another function to handle an array of previous cards before you call cc().

Make sense?

Wow, that’s a lot simpler than I anticipated. :sweat_smile: :rofl:

I could come up with some kind of function that passes a specific sequence through, and calling that function spits out the decision, but just for testing purposes…gosh I don’t know why I didn’t think just calling the cards line by line in sequence like that would’ve resulted in what was required. Oy.

Thank you!
