Using Hermes in React Native

React Native 0.64 introduced Hermes, an open-source JavaScript engine, as an opt-in feature for iOS, which significantly enhances the performance of mobile apps by reducing app launch times and precompiling JavaScript into efficient bytecode. With React Native 0.70, Hermes becomes the default engine, promising a shift in mobile app development by improving time to interactive (TTI), reducing binary and memory consumption sizes, and providing better user experiences. Hermes supports debugging through Chrome DevTools and enables developers to efficiently monitor performance metrics, contributing to a streamlined development process. The engine's integration with React Native has received favorable feedback from developers for its ability to enhance app performance and reduce bundle sizes, making it a preferred choice for building lightweight applications.
