>it’s all prioritisation of developer experience over user experience. And I have been saying this for well over a decade. Hopefully it catches on. I have always asked for example of sites done in React where I couldn't tell it is done in React or other JS Front End. The "at worst, hundreds of milliseconds" is precisely why Web Apps never felt as good as native apps. And if we collectively cant make web apps good, why not go back to Interactive Web Pages that is mostly Jank Free. I say mostly because it is still not Native Apps level.

> why does liking a tweet re-render the entire screen? They're probably using Redux, which has been the go-to for state management in React for nearly a decade. I've always been averse to it because it's implemented using contexts and triggers those full re-renders - it was designed during the class-based components era and relied on people actually implementing shouldComponentUpdate(), which isn't really a thing with modern function-based components. If they were using modern hook-based state management like Zustand or Valtio, full rerenders wouldn't happen.

  Redux uses context but does not do full re-renders except if you are using it wrong. It does a shallow compare on the object resulting from your selector to decide whether or not to re-render a component. That being said, none of the React projects I've had the chance of working on in the last 5 or 6 years has used Redux, so stating that it's been the go-to state management library for nearly a decade kind of sounds weird to me.
