Understanding How React Native Bridgeless Mode Reshapes Cross-Language Interaction

The introduction of Bridgeless mode in the React Native New Architecture significantly changes how JavaScript and native code communicate. The old architecture relied on a bridge for serialization and deserialization, which could introduce performance bottlenecks. Bridgeless mode, powered by JSI (JavaScript Interface), allows direct access between JavaScript and native interfaces. This fundamentally alters cross-language mechanisms, leading to faster communication and a more responsive user experience in your app. [IMAGE_PLACEER: Illustration of the React Native bridge vs. bridgeless communication]

Key Concepts Behind the React Native New Architecture

The React Native New Architecture introduces several core concepts that replace the old architecture’s bridge. Fabric is the new rendering system, designed to improve the rendering of native component instances. TurboModules enhance the performance of native modules by providing direct JavaScript access.
