I admire that the React team is focusing on performance. 👍

But, I find React is usually plenty fast without optimizations.

So:
1. I rarely use performance-oriented features like memo.
2. I find the UX improvement with these new features/patterns is often minimal.

1/3

For many apps:
1. Fetch waterfalls don’t exist.

2. Fetch after render has only a minor perf impact. It only impacts the initial page load, which is a tiny slice of the user experience.

3. Memo, useTransition, etc aren’t necessary. It already renders quickly.

So, I'm not saying these new React patterns and features aren't useful.

I'm just saying they're not typically necessary in my experience if I declare state as local as possible, and compose my components strategically.

3/3

Got some replies with "framework/library x is faster by default".

Yep. There are faster options than React today.

But my point is:
1. React is typically plenty fast by default.
2. Making it even faster for edge cases is trivial. Often via a one-liner like memo/useMemo.
