How to fix missing dependency warning when using useEffect React Hook?

This article is a good primer on fetching data with hooks: https://www.robinwieruch.de/react-hooks-fetch-data/

Essentially, include the fetch function definition inside useEffect:

useEffect(() => {
  const fetchBusinesses = () => {
    return fetch("theUrl"...
      // ...your fetch implementation
    );
  }

  fetchBusinesses();
}, []);
