Why does it automatically loop?

Question

I have a question about javascript.

At first, the result of the code below is "-1 Hold", but I'm wondering why does the part where I put mark ① automatically loops with the next arguments?

I was expecting that the function processes through of it and put the result with only one argument, then goes to the next arguments. So I expected "1 Bet", "1 Bet", "-1 Hold", "0 Hold", "-1 Hold" would be output as a result.

I couldn't find explanation about this since yesterday to now.. I'd be happy if somebody helps me.

* This is the URL of the task I'm talking about.

Here is the code.

   var count = 0;
    function cc(card) {
   ①  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;
       }   
    ② if (count > 0) {
        return count + " Bet";
      }
      else {
        return count + " Hold";
      }
    }
    
    cc(3); cc(7); cc("Q"); cc(8); cc("A");    //結果： -1 Hold

Thank you.

Answer 1

If you are using dev console to test it, it is simple. Only last command return value is shown (Not last line).

You should do something like

console.log(cc(3));
console.log(cc(7));
console.log(cc("Q"));
console.log(cc(8));
console.log(cc("A"));  

Answer 2

You can see when you are passing cc("A") it is decrementing the value.

 var count = 0; //1-> function cc(card) { 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; } if (count > 0) { return count + " Bet"; } else { return count + " Hold"; } } console.log(cc(3)); console.log(cc(7)); console.log(cc("Q")); console.log(cc(8)); console.log(cc("A"));

Answer 3

you are returning a string, but not doing anything with it. maybe you meant to write it like this:

var result = cc(3);

also its not good programming to mix strings and numbers like you are doing. when you write a function cc(card), you should decide if card is a string or a number. It will work fine as you have it, but it's not good coding.
