  1. This useEffect makes no sense, since you have a new loadItems instance in dependency array every render, the effect will execute all renders. You would get the same result without it, or improving the loadItems method

    1. Hey Rhoger! Thanks for pointing that out, you’re absolutely correct. While the loadItems function itself isn’t going to run on every render, as it’s “protected” by the ref, the useEffect hook will, which could definitely be optimised a bit better. This is what happens when trying to anticipate what the exhaustive deps eslint rule would indicate, without actually using a linter when writing the code 😬.
      To fix, we could either remove loadItems from the dependency array of the useEffect hook, and then add an eslint-disable-line comment, or we could wrap the loadItems function in a useCallback hook.

      Thanks again!
