One of the most sarcastic put-downs of a language I've ever seen.
It won't change anyone's mind; that's not its purpose.
It's meant to be funny. Don't take it too seriously. Read it for fun.

EDIT: We all know there are lots of reasons to use JS for a ton of use cases -- indeed, JS is currently the most widely used language on Stack Overflow: https://insights.stackoverflow.com/survey/2019#technology-_-... -- but that doesn't mean we can't recognize and laugh at the idiosyncrasies of the language :-)
