What does useObservableState do internally?

[nareshbhatia]

When I use useObservableState like this in my code, I am curious if the RxJS BehaviorSubject state is being copied into React state or am I using the RxJS state directly?

return (
  useObservableState<{
    data?: T;
    error?: string;
    isLoading: boolean;
  }>(result$) ?? { isLoading: true }
);

How does useObservableState work basically?

The RxJS BehaviorSubject value is being assigned(not copied) to React state.
