Keynote: Building React Native

on YouTube ↗40m

" summary

Explains that React Native is moving from an asynchronous JSON bridge to JSI and host objects so JavaScript can call native (Java/Obj‑C/C++) methods synchronously, with codegen for native modules and a Yoga layout engine handling flexbox to X/Y coordinates; outlines race conditions that cause input and scroll jank, shows a camera blob example where pointers avoid JSON copies, cites three‑thread runtime, ongoing Fabric/TurboModules work, and says the new architecture already exists in repositories and is tested in production by Facebook and other companies.
