How is the factorial calculated internally?

function box (num) {

                    if(num <= 1) {
                        return 1;
                    }
                } else {
                    return num * box(num-1);
                }
                alert(box(4));

this is recursive. The box function is called inside the box function and does not end the recursive call until the last time num-1 is less than or equal to 1.
