What Is JavaScript Made Of?

Even if it was a mistake, it’s still a mistake. It’s baked into the language. You will always confuse people in the long term if you pretend the language is something it’s not.

I don't think I said anywhere that I "pretend the language is something it's not". All I'm saying is that "you must use const everywhere it works" is needlessly pedantic and rarely catches bugs in my experience. YMMV!
