 # Basic Algorithm Scripting: Factorialize a Number

Basic Algorithm Scripting: Factorialize a Number

The challenge:
Return the factorial of the provided integer.

If the integer is represented with the letter n, a factorial is the product of all positive integers less than or equal to n.

Factorials are often represented with the shorthand notation n!

For example: 5! = 1 * 2 * 3 * 4 * 5 = 120

Only integers greater than or equal to zero will be supplied to the function.

My code:

``````var arr = [];
var newArr = [];
function factorialize(num) {
if (num == 0) {
var forZero = 1;
return forZero;
} else {
for (var i = 1; i <= num ; i++) {
var product = arr.push(i);
}
console.log(arr);
newArr = arr.reduce(
(counter, current) => counter * current);
return newArr;
}
}
factorialize(10);
``````

My problem:
Even though my code is returning the right answers, when I run it, the test won’t accept them and give me the check marks for all each of the requirements.
