# Why switch statement is recommended over if else

Tell us what’s happening:
Cards Sequence 2, J, 9, 2, 7 should return

1 Bet

I think it should return 0 Hold, not sure why this condition is not satisfied

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 ++;
break;
case 10:
case "J":
case "Q":
case "K":
case "A":
count --;
break;
case 7:
case 8:
case 9:
count = 0;
break;
}
var holdbet = 'Hold'
if (count > 0) {
holdbet = 'Bet'
}

return count + " " + holdbet;

// Only change code above this line
}

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

Challenge: Counting Cards

Take a look at hint #1 in the challenge

the 2 raise by 1
so count is 1
the J lower by 1
so count is 0
9 does nothing
so count is 9
2 raise by 1
so count is 1
7 do nothing
so count is 1

when count is 1, function returns "Bet", so "1 Bet"

Do NOT reset count to 0 when value is 7, 8, or 9.
