Thanks a lot for the response. Your comment about constraints improving design makes a lot of sense. As to libs similar to React, I assume you're talking about Mercury and Mithrill. But I'm quite happy with React's performance and escape latches (shouldComponentUpdate). I'll however switch in a heartbeat if a better design comes along. The problem is that unlike when I was mutating DOM with spaghetti JS or wrangling with Angular, I am yet to say "why is this thing so darn difficult" with React for almost all use cases I've thrown at it (yet to figure out animations). And the last React.js Conf has taken care of most things that I could imagine improving in web development with Relay and CSS in JS.
