I think this person needs to think in terms of a series of onboarding ramps. You aren't going to learn to fly a commercial jet from nothing. You might want to get a private license first. Before that you learned to walk, talk, read, write and add up. In other words, learn JS proficiently without any libraries first. Then learn basic react, maybe without all the complex toolchains - just include the CDN link that compiles the code on the page and grok React. Then finally do some basic React coding without the Redux etc.
