alert("2+2=" + (min(2,2,3)+min(2,3,2)));

can I make javascript stop being a wuss and assign 3 to "num" when I do:
var func = 3;
var num = func(1,2,3);

min = function(num1, num2, num3)
{
    min = num1;

    if (num2<min)
    {
        min = num2;
    }

    if (num3<min)
    {
        return num3;
    }
    else
    {
        return min;
    }

}

alert("2+2=" + (min(3,5,2)+min(3,5,2)));

min = function(num1, num2, num3)
{
    min = num1;

    if (num2<min)
    {
        min = num2;
    }

    if (num3<min)
    {
        return num3;
    }
    else
    {
        return min;
    }

}
alert("2+2=" + (min(3,5,2)+min),(3,5,2));
