Judging by the site, they don't have insightful answers to these questions. It's broken with weird artifacts, errors, and amateurish console printing in PROD.
Alas, I did not realize I was being held to the standard of having no bugs under any circumstance, and printing nothing to the console.
I have removed the amateurish log entries, I am pitiably sorry for any offense they may have caused. I will be sure to artisanally hand-write all my code from now on, to atone for the enormity of my sin.
