Because all of those who started on something like C, C++, or Java have way better programming practices? My experience tells me that starting language is literally not a vector in determining how good of a programmer someone is.

I agree. Maybe its the barrier to entry for publishing that has gotten a lot lower and thus pushing down the quality of public code (which is natural). Or maybe im just worried about everything being pushed to the browser.

This is absolutely nonsense. Modern JavaScript is powerful and actually quite elegant. Perhaps stop thinking about the crappy JavaScript people wrote >10 years ago.

Maybe some are. There is however nothing nothing elegant about running 5 massive electron, node etc apps in your browser w. 60% code overlap grinding everything to a halt. Its not so much the language but how its being used.
