This comes off as very naive and contrarian, and like the author just wanted a reason to create some more javascript libraries. The lack of types in your library makes it harder to use, more likely there will be bugs where its being used, and the library itself is probably buggy. The author commonly champions bad practices, that you should "just know" how js works and then none of this matters. There's very strong reasons a vast amount of people are switching to typescript. It can very easily compile to clean javascript, you can commit that to git, and you are much better off.
