Example of "global" hook utilizing react context

useJimbo.js

import React, { useContext, useState } from 'react';

const initialState = 'Jimbo';
const JimboContext = React.createContext(initialState, () => {});

export const JimboProvider = ({ children }) => {
  const [state, setState] = useState(initialState);
  return (
    <JimboContext.Provider value={[state, setState]}>
      {children}
    </JimboContext.Provider>
  );
};

const useJimbo = () => {
  const [state, setState] = useContext(JimboContext);
  return [state, setState];
};

export default useJimbo;
