Basic JavaScript - Counting Cards

Tell us what’s happening:
Describe your issue in detail here.

This code should work. The debugger is not very helpful

``````let count = 0;

function cc(card) {
// Only change code below this line

if (card > 1 || < 7) {
count++;
}
else if (card == 10 || 'J' || 'Q' || 'K' || 'A') {
count--;
}
if (count > 0) { return count + "Bet";
}
if (count <0) { return count + "Hold";
}

return "Change Me";
// Only change code above this line
}

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

Challenge: Basic JavaScript - Counting Cards

This is not how you write an if statement with multiple conditions

This is not checking what you think it is checking. You might want to review how to make multiple comparisons with the same variable.

if (card >= 2 || card <= 6) {
count++;

Did you fix the other conditional?

let count = 0;

function cc(card) {

// Only change code below this line

if (card >= 2 || card <= 6) {

count++;

}

else if (card == 10 || ‘J’ || ‘Q’ || ‘K’ || ‘A’) {

count–;

}

if (count > 0) { return count + ‘Bet’;

}

else if (count < 0) { return count + ‘Hold’;

}

// Only change code above this line

}

cc(2); cc(3); cc(7); cc(‘K’); cc(‘A’);

Still error

Your function should return a value for count and the text (

``````Bet
``````

or

``````Hold
``````

) with one space character between them. Cards Sequence 2, 3, 4, 5, 6 should return the string

``````5 Bet
``````

Cards Sequence 7, 8, 9 should return the string

``````0 Hold
``````

Cards Sequence 10, J, Q, K, A should return the string

``````-5 Hold
``````

Cards Sequence 3, 7, Q, 8, A should return the string

``````-1 Hold
``````

Cards Sequence 2, J, 9, 2, 7 should return the string

``````1 Bet
``````

Cards Sequence 2, 2, 10 should return the string

``````1 Bet
``````

Cards Sequence 3, 2, A, 10, K should return the string

``````-1 Hold
``````

Yup. You have more bugs. Did you try console logging the output.

That is the output i posted. Weird problem. It should be right. Im gonna skip

You posted the test output.

You have no debugging statements.

You should manually run a test case and look at the output with a console.log statement

This code should work. Bizarre.

``````let count = 0;

function cc(card) {
// Only change code below this line

if (card > 1 && card < 7) {
count++;
} else if (card == 10 || 'J' || 'Q' || 'K' || 'A') {
count--;
}

if (count > 0) return count + " Bet";
return count + " Hold";

return "Change Me";
// Only change code above this line
}

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

You should fix this, like i saif above.

this if statement will return true if card is 10
but will also return true if card is not 10
that’s because you said || ‘J’ etc.
and ‘J’ is always true (J is J and it is not false, therefore it is true)

let count = 0;

function cc(card) {
// Only change code below this line
var regex = /[JQKA]/;
if (card > 1 && card < 7) {
count++;
}
else if (card === 10 || regex.test(card)) {
count–;
}
if (count > 0) { return count + " Bet"; }
if (count < 0) { return count + " Hold";}

// Only change code above this line
}

cc(2); cc(3); cc(7); cc(‘K’); cc(‘A’);

This is as close as im going to get without copying the solution.

MY only error is

Cards Sequence 7, 8, 9 should return the string

``````0 Hold
``````

if (card >= 7 || card <= 9 ) { return count; }

I added in that syntax to make the count neither count up or count down but i am not sure if this is correct

What happens when count is 0?

Return stops the function

Well i assumed that much. I have no other way to continue the count without adding or subtracting. Do you?

In C++ i could just say

if (count = 0) { continue ; }

Why do you need a continue? Why not just not omit that if case?

The system needs to know what to do if i 7 , 8 or 9 is pulled
