The State of React Native

on YouTube ↗28m

" summary

React Native is moving from an async‑everywhere model to an architecture that makes the shadow tree immutable and able to run on any thread so that synchronous high‑priority updates (scroll, text input, taps) avoid round trips to JavaScript, reducing FlatList and marketplace tab jank and the text‑input frame drops that show up at high typing speeds. Changes include Yoga, Metro, replacing JSC with other engines (V8), tighter C++ boundaries with React Fiber influences and a long‑term rollout rather than immediate flip.
