@LonePoop You just need to declare the 'total' variable inside the function scope.

function factorialize(num) { var total = 1; for (var i=0; i<num; i++){ total = total * (num - i); } return total; } factorialize(5);

function factorialize(num) {
return (num !== 0) ? num * factorialize(num - 1) : 1;
}
