Nice article, and I'm actually about to make a video on this exact same subject!

I noticed that when you do the for loop, there's i = 0, instead of let i = 0, and this could result in the creation (or mutation) of a global variable. Funny enough, i is a global variable on at the moment, and it's value is 0! But once you run the code above, it gets updated.

Good job on this article!
