TIL: You can actually embed `console.log` directly inside JSX for quick debugging! 🤯 Sounds obvious, but I always placed mine above the return

I've encountered this VSCode extension today It's pretty cool, it not only let's just know if a component is handled by react-compiler, it also let you see the output of react-compiler directly in VSCode That's cool so you can easily see what the output is instead of guessing
Started using React Compiler Marker with @Expo and there's no going back—I'm in LOVE 🚀 Shows you ✨ inline when a component is auto-memoized (useMemo, useCallback, etc) or when React Compiler 🚫 failed and you need to follow Rules of React. =blazejkustra.react-compiler-marker

Imagining UI components as jelly is oddly satisfying… this time it’s a “Jelly Switch”, built using TypeGPU without any extra libraries. Live demo & Code: https://t.co/QPGZ9dnLSA Once again, SDFs gave us a lot of freedom to make the form of the object dynamic and jiggly. Konrad
Ever since I first saw this I wanted to try implementing it in TypeGPU, and I finally got around to it while testing the new 0.8 release. You can try out the Jelly Slider here: https://t.co/2qi5c8kP5x Had a lot of fun brainstorming optimisations with @iwoplaza and the team, and
