I saw the video by that other dude(ui.dev), now that I see yours, I embrace my love for Typescript, again, even more. It would be cool if you linked that dude's video here so that people can see his way of solving this bug in vannila js. And who's that girl at the end!?

Isn't there a bug on line 1 as well? Pretty sure optional parameters need to be declared at the end, so the first argument being declared as a blank array is incorrect.
