@schemeless/event-store-react-native/dist/queue/makeObserverQueue.js

React Native compatible build of the [`@schemeless/event-store`](../event-store) runtime. It mirrors the Node.js implementation but swaps the internal queue implementation to [`react-native-better-queue`](https://github.com/YahyaASadiq/react-native-better
