JS: Card Counting, help debugging - Why can I not identify 10?

Tell us what’s happening: I seem to be having trouble passing a card equaling ten through my script. I have tried using strict (===) and non-strict (==) comparisons, but neither seem to work for having the script recognize that the ten should decrease overall count.

All other parts of the script appear to be working as intended.

Help identifying the issue would be appreciated! Thanks!

Your code so far

var count = 0;
var decision = 0;

function cc(card) {
  // Only change code below this line
if (card < 7) {
} else if (card > 6 || card < 10) {
  count = count + 0;
} else if (card == 10 || card == "J" || card == "Q" || card == "K" || card == "A") {
if (count > 0) {
  decision = "Bet";
} else decision = "Hold";
  return count + " " + decision;
  // Only change code above this line

// Add/remove calls to test your function.
// Note: Only the last will display
cc(10); cc("J"); cc("Q"); cc("K"); cc("A");

what happens to make you say that it doesn’t work?

You made a mistake in your logic

What happens when 10 hits this?
else if (card > 6 || card < 10)

@ilenia - the console.log results for passing a ten through the function result in a zero rather than a -1.

@broregard - it shouldn’t so anything? That logic statement should only apply to 7, 8 and 9. Is there something I am missing on it…?

@Tierney When 10 is passed to the function, the first if statement condition evaluates to false, so your else if (mentioned by @broregard above) is evaluated. Your condition checks if card is greater than 6 OR card is less than 10. Since 10 is greater than 6, this else if statement condition evaluates to true, so you add 0 to count (which does not change count).

Instead, if card is 10, you should be subtracting 1 from count.

NOTE: When you have two conditions separated by the || (OR) operator, it only takes one of the conditions evaluating to true to make the entire statement evaluate to true.
