Hi Nicholas,

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:

The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't

import { merge } from 'lodash'

// This module allows us to completely customize all of Material UI's JSS stylesheets
// to define our own theme.
//
// Note that you Material UI's JSS is often tied to application logic and you may 
// deviate from the official Material UI spec.
// 
// Unlike using the `overrides` feature of jss-theme-reactor, here you have access to
// the original calculated styles and theme. Notably you can do deep merge (lodash.merge)
