Counting cards round 2 I will fix this but could use some hints

Curriculum Help

Tell us what’s happening:
As far as I get the lesson
This is what I must do
If one of the numbers are

[ 2, 3, 4, 5, 6 ] + 1
[ 7, 8, 9 ] + 0
[ 10, J, Q, K, A ] - 1

They also need a card parameter
and a count variable

I revieuwd this: JavaScript else Statement
and: JavaScript Comparison Operators

Your code so far


var count = 0;

function cc(card) {
 // Only change code below this line
if (card == 2, 3, 4, 5, 6) {
 count = +1;
} 
else if (card == 7, 8, 9) {
 count = +0;
} 
else (card == 10, 'J', 'Q', 'K', 'A') {
 count = -1;
}

 // 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');
