Tips for Making Effect Code More Declarative and Managing Imperative Styles

// this whole "helper" should have never appeared
// models tried to extract pieces of code 
// to preserve imperative control flows
const loadNext = Effect.flatMap(loadNextContext, ({ state, token }) =>
  Effect.map(
    // it tried to use Option.toArray as "if" here :(
    Effect.forEach(Option.toArray(token), loadNextPage),
    // then it managed to insert another branching flow to check for Effect ran 
    (results) => Option.getOrElse(A.head(results), () => state),
  ),
);

const loadNext = Effect.flatMap(
  SubscriptionRef.get(tradesRef),
  (state) =>
    Option.match(state.nextToken, {
      onNone: () => Effect.succeed(state),
      onSome: loadNextPage,
    }),
);
