Can a library have compiler?)
What they've added is wrapping your code in more memoization functions, basically. All stuff that doesn't fundamentally transform the code, aside from inserting more `useMemo` and the like.
The JSX macro - which is itself already optional but everyone uses it - is just that, a handy macro with implementations available in every common bundler and transpiler out there.
React Compiler is just a babel plugin for automatic performance improvement, memoization specifically, for never perfectly memoized React code.
Can library have compiler? Well why can't it? For example stdlib has a compiler, because C does.
As for anything that has patterns of building with, will argue it's a framework.
If you don't use them, then React is quite literally no different to you.
Hooks themselves are just a solution to async code, but the implication was that react was no longer a state-based UI rendering library and became a full blown frontend framework.
Hooks solution to async code? Hooks make React full blown forntend framework? Routing only important for single page applications? Yellow gorilla bread butter? Chickity dickity web frontend back single page I understand much
These are examples for React frameworks: https://react.dev/learn/start-a-new-react-project#production...
Next.js is a React framework.
If Payload is a framework or not is debatable. I think it's more like a data layer around a database for a any js app and an Admin Panel (that uses Next.js now). It might be called a framework for your own Headless CMS, because it is code first. So you basically code the panel and the data structure yourself.
