The state of React Native
summary
React Native is being re‑architected to make the UI layer thread safe by moving to an immutable shadow tree and a C++ implemented UI management module, plus a new bridge that supports prioritized synchronous and asynchronous calls. Facebook pilots the new stack on small screens in iOS and Android and reports no major memory or perf issues so far. The goals are to enable synchronous rendering and layout on any thread, reduce TTI and jank for things like text input and scrolling, and scale to apps like Marketplace used by 800 million users.
