This Week In React 157

Concurrent Mode, RSC DevTools Extension, Gatsby, Radix asChild, Suspense, hydration, useMemo, React-Redux, Fresh, TinyBase, Worklets, TFLite, local_modules, Bootsplash...

Hi everyone!

It's been pretty quiet on the React front this week, but we've still got a few nice articles to read.

On the React-Native side, Marc Rousavy is on fire, publishing a number of packages that seem to herald the imminent arrival of VisionCamera v3.

We should have some nice releases soon, like 🐦 Bun 1.0, 🐦 Astro 3.0 and 🐦 TanStack Router.

I'm taking a short break next week, so I'll see you on 6 September 👋
