Optimizing the React Native Threading Bridge.

In mobile applications, the performance barrier often lies in the interface layer between JavaScript and the native threads. Sending large payload serialized packets over asynchronous bridges creates frame drops and UI lags.

Using the modern JSI (JavaScript Interface) allows direct reference passing from JS engines to C++ native structures. This bypasses serialization entirely, allowing high-performance audio, video, or data telemetry handlers to operate synchronously at native execution speeds.

Furthermore, isolating complex analytical computations off the main React Native UI thread onto dedicated background worker pools keeps screen rendering loops running at 120Hz, ensuring absolute buttery smooth scrolls on high-refresh-rate devices.
