I modified the above solution with some console.log statements, so you can see the value of the variables at each step of the way. Also, I have blurred your solution, so as not to spoil the solution for others.

```
function factorialize(num) {
for(i = 1; num >= 1 ; num--) {
console.log('start of iteration i = ' + i);
console.log('num = ' + num);
i = num * i;
console.log('after reassigning num * i to i, i = '+i);
console.log(); // line break to separate iterations
}
return i;
}
factorialize(5);
```

```
The output of the above is:
> start of iteration i = 1
> num = 5
> after reassigning num * i to i, i = 5
>
> start of iteration i = 5
> num = 4
> after reassigning num * i to i, i = 20
>
> start of iteration i = 20
> num = 3
> after reassigning num * i to i, i = 60
>
> start of iteration i = 60
> num = 2
> after reassigning num * i to i, i = 120
>
> start of iteration i = 120
> num = 1
> after reassigning num * i to i, i = 120
>
> => 120
