How Hermes improves React Native performance
- The time it takes for the app to become usable, called time to interact (TTI)
- The download size (on Android, APK size)
- Memory utilization
To start using Hermes, developers will need to make a few changes to their build.gradle files and recompile the app. See the full instructions for the migration to use Hermes on React Native.
