You should start with React, honestly. Learning React is a bit about learning the framework but in order to be a good react dev, you mainly need to know how to write some good JS. React views are not templates, they are just javascript function calls (JSX is just some sugar on top of some JS function calls).

After that you can basically try anything, but at least you will know pretty much everything about what modern JS has to offer!

I would recommend starting with create react app [1]. I think it can be used with other libs than react as well, the thing is just a strong webpack + eslint preconfiguration so you don't have to worry about it.

I second it. If you are starting out, React is the way to go. Of all the frameworks I have tried, React is the one that seems most "sane" to me. Either React or Elm.
