> React can render at more than 60fps if necessary, and if the code isn't shit.

Sorry, that doesn't really come across as a ringing endorsement. React apps are typically not doing anything complex so rendering at less than 60fps should only happen if you're doing very computationally intensive things or writing bottom-quartile quality code.

Yeah, obviously your average React app has no need to render anywhere near that frequently. The ones I've worked on will generally only render as a response to user action, server event or polling.

I'm just saying they can render that fast. So if your app takes a second (or several) to render it's obviously not because react is slow, it's because the code is ass.

In most cases if a React app takes a long time to render a page it isn't really rendering that's taking time, it's a slow network call or multiple. So the app being slow has nothing to do with React at all, it's the backend code that's slow or it's the frontend code doing multiple consecutive requests or something like that.

All I'm saying is react is not the reason it's slow.
