Factorialize a Number! wondering if it works

Tell us what’s happening:
my code is working on the console.log, but with the tutorial it is not. is it a problem with my algorithm? i wanted to use recursion becuase i am taking algorithm class in school right now, do i have to use a for loop ?

Your code so far

var i=1;
function factorialize(num) {
if (num>1){
i = i*num
return i;

Link to the challenge:

You’re using a global variable, that won’t work because it will update each test (first one will be correct, then i will start as the result of that and so on). It’s fine to use recursion, but that would not be how you do it.

got it, thank you! recursion is still confusing for me and i shouldn’t use it in these tutorials.
weird enough, when i copy and paste the code on my editor and run it, it actually works with any number i try.
