You are not allowed to call `reduce`

on an empty array without an initial value. Passing a “initial value” of 1 solves the problem.

```
function factorialize(num){
var array = [];
for(var i = 1; i <= num; i++){
array.push(i);
}
factor = array.reduce(function(a,b){
return a*b;
}, 1);
return factor;
}
```
