useGlobalState | simple state management from react to react | Frontend Utils library

In my React Native code, I've been using Hookstate as my state manager (in this case to see if the user is signed in or not). While my auth flow does show the home page for a second after tapping the log in button, an error then pops up (as shown in the title).

Below is my implementation for the Hookstate state:

I am currently working on a project provided by frontendmentor.io called Rest Countries API.

Here I am trying to get a single country, and with the help of 3 letter codes in the borders array, I am trying to get names of the border countries. But they won't appear in the browser. Can anyone help? What am I missing? Thanks In Advance

For the web app I'm building in React, I need to record audio and be able to somehow put that recorded audio in the app's global state so I can use and manipulate that recorded audio in different components of the app.

My global state is setup using React Hooks (made and managed with useReducer, createContext, useContext) and I believe Hooks only work for functional components, not class components.

So the issue I'm running up against is that every tutorial I've followed to get my browser microphone to work uses class components (like the code below), not functional components. And I'm assuming that this is for good reason because when I've tried to translate these class components into functional components, I get the error: "cannot read property 'finish' of 'undefined'"

Are there ways to take this audio data (blobURL) and pass it to my global state?

Alternatively (and ideally), is there a way to use the microphone to record audio in a functional component instead of a class component?

I´m creating a new instacne of a map component in the useEffect hook with second parameter [] so it only runs once.

After creating the instance I want to register a callback, which is fired if the user interacts with the map. Inside this callback I want to access the state of my component. How can I do this, without causing a loop? If I don´t add my state to the second parameter the state stays the same with every run of the callback (as expected), but if I add it, I cause a loop.
