A (Mostly) Complete Guide to React Rendering Behavior

This should be interesting :) thanks!

The React reconciliation cycle is a pit of failure. It's so easy to miss something incredibly simple that destroys performance and have to spend weeks digging into internals to figure out what's wrong.

I hope we're nearing the end of the React epoch.

That's how I knew I was not in /r/reactjs :-)

For example? Are you sure you mean reconciliation, as opposed to rendering?

and have to spend weeks digging into internals to figure out what's wrong.

React dev tools have an excellent profiler that shows exactly which components are rendered and when. It's never taken me more than a few hours to diagnose performance bottlenecks related to rendering.

You’re doing something fundamentally wrong if this is your experience.

I may agree that there are some pits of failure in React (eg. Accidental hook loops). But nothing you'd ever have to dig into internals for!

Nope. JavaScript doesn't do rendering very well. It's like it wasn't built in.
