Welcome to Issue #18! This week, we are looking under the hood at the mechanics that make modern apps feel "liquid." We start with a massive performance audit from the Expo team. They’ve benchmarked every major animation approach available in 2026—if you’re still debating between CSS-interop and Reanimated, the data in this post will likely settle it for you. We also dive into the technical wizardry of React's Streaming SSR. It’s one thing to see a loading spinner; it’s another to understand how React literally pipes HTML chunks out of order and re-assembles them in the DOM without a flicker. For the mobile-first crowd, VisionCamera v5 is setting a new bar for scanning speed, and we have the latest on the Xcode 26 requirements from Apple. Let’s get into the details!
