I'm able to make what people call a "web app", yet I honestly have no idea what React and Redux are, besides buzzwords, and what they are supposed to solve.
But then there's also the problem of people relying on JavaScript at all for websites that would've been fine as a bunch of fully static HTML pages. It's as if these days you can't do software development without overengineering everything into oblivion.
You haven't at all responded to your parent comment whose premise was that many frontend devs cannot utilize the freedom that you are apparently enjoying.
IMO it's not the topic here if JS should at all be used. You won't catch me arguing with that -- my answer is almost always "NO!".
The topic was: "but can you make web pages like 20 years ago in the current frontend dev jobs market?" -- the answer that is "no" as well IMO.
