Understanding the bridge that connects the JavaScript thread to native modules is crucial for optimizing performance in React Native apps. Can someone explain the core mechanisms behind this communication layer, including how data is serialized and transferred? Additionally, what are the common pitfalls developers encounter when relying heavily on the bridge, and are there recommended patterns to minimize its overhead? I’d appreciate any insights or resources you’ve found helpful.
How does React Native's bridge handle communication between JavaScript and native code?

Thanks for the detailed question! The bridge serializes JavaScript objects into a JSON-like format and queues them over a single thread to native modules (and back), batching calls to cut down on overhead, while heavy data processing can be offloaded to native code or newer JSI/TurboModules to avoid the bridge bottleneck. Have you experimented with those patterns yet?
