Ask HN: Coming from server/client, what client js framework to pickup?

Angular? Metereor? other? Thanks

Is react only for front end gui work?

Yes, react is just the "View" of your app

Now React has so big ecosystem (Redux, a lot of components, many libs) that I can say it is a reliable framework for creating Web applications.

If your looking from a job perspective then do a job search with that as a keyword and see what comes up the most in your city.

Just based on your interest...
