JSI is one of the coming/new features of React Native.

Basically, JSI removes the bridge between JS and the Native side. The latest react native versions (e.g. 0.65) have "already" some JSI support. There are a couple of new libraries that are already using JSI and they are over 10x faster than their counterparts: e.g. react-native-mmkv and react-native-quick-sqlite. However, Realm-JS seems to already call JavaScriptCore APIs directly, so JSI might not make so much difference.

it seems like there are at least some planning about JSI in the Hermes PR draft: https://github.com/realm/realm-js/pull/3792.

Are there some official plans to start using JSI? Would JSI make Realm faster or is it needed just for Hermes support?

In other words, can we anticipate better perfomance in the future?
