React Native Runtimes Enables Multi-Threaded JavaScript to Keep UI Smooth
React Native Runtimes adds support for multiple named JavaScript runtimes, letting components and functions run on secondary threads while the main UI thread stays free. It ships two libraries – @react-native-runtimes/core for runtime composition and @react-native-runtimes/state for synchronized native-backed state – enabling smoother lists, chat, sync, and crypto workloads.
