"My language that I use all the time (definitely no Blub paradox here) isn't bad, look at all these random features it has!" Sorry, but that isn't a reasonable argument. Having used all the stuff you mentioned, and many other languages, JS is relatively not good.

Is essentially an entirely different language. But I agree, it's a vast improvement.

But the language doesn't actively assist in precluding low-quality code, and most production JS that wasn't transpiled is low-quality.
