Guys, could you please help me out?
I am stuck in this challenge:
In the casino game Blackjack, a player can gain an advantage over the house by keeping track of the relative number of high and low cards remaining in the deck. This is called Card Counting.
Having more high cards remaining in the deck favors the player. Each card is assigned a value according to the table below. When the count is positive, the player should bet high. When the count is zero or negative, the player should bet low.
Count Change | Cards |
---|---|
+1 | 2, 3, 4, 5, 6 |
0 | 7, 8, 9 |
-1 | 10, ‘J’, ‘Q’, ‘K’, ‘A’ |
You will write a card counting function. It will receive a card
parameter, which can be a number or a string, and increment or decrement the global count
variable according to the card’s value (see table). The function will then return a string with the current count and the string Bet
if the count is positive, or Hold
if the count is zero or negative. The current count and the player’s decision ( Bet
or Hold
) should be separated by a single space.
Example Output
-3 Hold
5 Bet
Hint
Do NOT reset count
to 0 when value is 7, 8, or 9.
Do NOT return an array.
Do NOT include quotes (single or double) in the output.

And here is my solution:
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 = 1;
break;
case 7:
case 8:
case 9:
count = 0;
break;
case 10:
case 'J':
case 'Q':
case 'K':
case 'A':
count = -1;
break;
}
var count = count + card;
if (count > 0) {
return console.log(count + ' Bet');
} else {
return console.log(count + ' Hold');
}
// Only change code above this line
}
cc(2);
