I think it sums up the Beginner Community in general, not the JS community. You see this with beginners in everything.
You take the struggles of a beginner as an indictment on the broader professional JS development community?
It has nothing to do with them being a "beginner".
My reaction to your comment is likewise ineffable and mysterious.
The JavaScript "community" feels like more a large country.
I believe (and hope) this is not representative of the JS community.
Given that front ends have a huge visual component, it kind of makes sense that developers would approach them like clothing fashion: you don't have to watch the designers to look reasonably good, or even pay attention to construction, you just have to watch everyone else.
Well, at least that's what I picked up from this rather honest opinion.
