One of the things I love about React and React Native is that it's possible to use them from "plain old JavaScript" (React.createElement and friends). And I work at le Goog; my org has mandated Polymer 2+TypeScript for all new desktop web code. Sure, maybe in production you want to use JSX and/or TypeScript, but learning a new language and a new framework together is overwhelming, period. Pedagogically, it makes it hard to conceptually separate what is a language feature and what is a framework feature. (To this day, I still have trouble separating what parts are Ruby and what parts are Rails.)
