Dealing with Side Effects with the useEffect() Hook

In order to deal with side effects such as the HTTP request shown previously in a safe way (that is, without creating an infinite loop), React offers another core Hook: the useEffect() Hook.

  const blogPosts = await response.json();
  return blogPosts;
}
function BlogPosts() {
  const [loadedPosts, setLoadedPosts] = useState([]);
  useEffect(function () {
    fetchPosts().then((fetchedPosts) => setLoadedPosts(fetchedPosts));
  }, []);
  return (
    <ul className={classes.posts}>
      {loadedPosts...
