Leveraging React Native JSI to enhance speed and performance

React Native is a cross-platform mobile app development framework that facilitates communication between JavaScript and platform-specific languages like Java and Objective-C through two main architectures: the classic bridge architecture and the newer JavaScript Interface (JSI) architecture. The bridge, part of the classic architecture, asynchronously handles communication between JavaScript and platform UI threads, but can lead to performance issues such as slower start times and poor user experience during UI interactions. The new architecture using JSI allows direct and synchronous communication, reducing start times and improving performance by enabling features like TurboModules and Fabric for efficient module loading and UI rendering. To demonstrate the advantages of the new architecture, the text outlines the creation of TurboModules for retrieving a device's name and converting measurement units, showcasing how JSI enhances app performance and development efficiency. This exploration provides a solid foundation for leveraging React Native's new architecture to build more responsive mobile applications.
