If you're working with React Native, you’ve probably heard of Hermes—a lightweight JavaScript engine designed specifically to enhance performance. But how does it actually make a difference? ??

?? What is Hermes?

Hermes is an optimized JavaScript engine built by Meta for React Native apps. It improves startup times, reduces memory usage, and enhances overall app responsiveness.

?? How Hermes Supercharges React Native Apps:

? Faster Startup – Precompiles JavaScript to bytecode, reducing parsing time. ? Lower Memory Usage – Efficient garbage collection and optimized memory footprint. ? Reduced App Size – Smaller binary sizes lead to better performance on low-end devices. ? Better Performance Debugging – Includes the Hermes Inspector for improved debugging.

?? How to Enable Hermes in Your React Native App

If you're using React Native 0.64+, enabling Hermes is simple:

enableHermes: true

3?? Run the following commands:
