I've found myself needing to learn React on the go while working on an evolving React codebase, and needing to improve performance significantly and it's been very hard because casually googling for how to do things in React yields lousy hits full of extremely high level "babys first react todo app/blog" type articles. Absolutely not what I need. What I want to know is how to build things with React as performant as possible. This discussion of complex and performant apps seems elusive.
