Hermes

Hermes is an open-source JavaScript engine optimized for React Native. It's written in C++ and designed to improve app performance, reduce load times, and decrease memory usage on mobile devices. Hermes supports the latest JavaScript features while compiling code ahead of time into efficient bytecode during app build stages instead of just-in-time at runtime. This approach allows for faster startup times and a better user experience by lowering the overhead traditionally associated with interpreting JavaScript directly on mobile devices.
