Async functions with React's useEffect hook

It may not be pretty, but the easiest way to call an async function in useEffect is to use an Immediately Invoked Function Expression (IIFE).

useEffect(() => {
  (async () => {
    try {
      await doSomething();
    } catch (err) {
      console.error(err);
    }
  })();
}, []);

That's it! Don't overthink it.
