React Native gives your product one main JavaScript runtime. When a feed, chat screen, editor, reducer, or hydration job monopolizes that runtime, input, animation, and navigation all start competing for the same VM. react-native-runtimes adds a multi-runtime layer for React Native New Architecture apps: - mount selected React components in named secondary Hermes runtimes - run whole screens, headless tasks, and typed functions away from the main runtime - share state across isolated JS heaps through a native C++ singleton - prewarm runtimes before navigation so expensive surfaces are ready when users arrive - wire it through Metro and, for Expo, a config plugin instead of hand-written runtime plumbing --- What it unlocks If your app has... You can move...
