I was hoping React Compiler would only rerender children if their sliced part of a larger state was updated - unfortunately all children gets updated :'(
Curios what the recommended way is to solve this while not opting out of concurrent rendering? playground.react.dev#N4Igzg9grgTg...

Having fun building my own scheduler component! Currently focusing on getting the interactions and layout feel right and smooth, with proper keyboard support. Recurring event support also in the works!

Toying with patterns to update css variable without triggering rerenders. Is the anti-useEffect crowd ok with this use case? (cc @tkdodo.eu)

7 years ago Apple had to fight rumours about macOS slowly being replaced by iOS due to iOS getting more advanced and a perceived lack of investment in macOS, to the point they had to address this in a keynote. And people *still* didn't believe them. Feels like where React is today with RSC vs SPA.

omg i just searched for ref 😭 thanks! i sort of expected to find a single page about the ref property. maybe consider increasing the number of hits even on small search queries, if algolia allows for that?

Absolutely, we use `select` quite a bit, but I think it needs to be returned as compatible with the InfiniteData type, meaning wrapped in { pages, pageParams}? We simplify this in our wrapper with a Proxy (the spreading in the last post was a simplification).
