I answer WHY and HOW we compile JS/TS to WGSL, how it improves interop for the whole ecosystem, and the added dimension of customizability it unlocks for WebGPU libraries

@samuel.bsky.team can we have a better separation between "Show more like this" and "Show less like this"? The buttons are quite small and I often fat-finger the wrong one trying to customize my feed 😢

We have just released an RC version of Reanimated, 3.17.0-rc.0 🥳
It has significant changes in the native code structure. It's an important milestone for our goal of moving Worklets to a separate library.
If you can, please check if it compiles in your project 🙏
All feedback is welcome!
