> learning modern React ecosystem from the scratch is no easy undertaking even for experienced developer. Strong disagree on this. Modern Angular and Vue work almost identically to React. The details are different, but the principles the same. For an experienced dev, that knowledge should translate directly. The ecosystem is also not that bit. React Router and some state management tools are the only React-specific libraries one really needs. The rest you can lookup. The trickiest tooling in the JavaScript ecosystem has always been the build tooling, and that's largely shared across frameworks.
