I guess we just disagree over whether or not all that is made easier with React. I have worked on large jQuery codebases that do everything you mentioned: they are maintainable, they manage state in a comprehensive fashion, and they are modularized. JavaScript Fatigue inducing media tries to taint jQuery calling it all sorts of things but that hasn't stopped me. Sure you need to learn and use a handful of useful patterns to build with it, but it's the same situation if you want to make proper use of any framework. And I updated the url for my demo :)
