Exploring React Native’s new architecture

The upcoming version of React Native introduces significant changes to its architecture, particularly with the new TurboModule system and the Fabric Renderer, enhancing the interoperability and rendering process. The Fabric Renderer, implemented in C++, aims to improve the synchronization between JavaScript and native threads, along with better interoperability with host platforms like Android and iOS. This allows for more consistent and seamless integration across various platforms. The rendering process in Fabric occurs in three phases: Render, Commit, and Mount, each contributing to a more efficient rendering pipeline. TurboModules, an enhancement over Native Modules, enable on-demand loading of native modules, which optimizes startup time and reduces memory usage. The new architecture also facilitates easier development for Smart TVs and improves data fetching with features like React Suspense and Concurrent Features from React 18. These changes promise to enhance developer experience and application performance while also simplifying the process of building cross-platform applications.
