I made this once, but never used it. I'm dropping it here incase I need it someday.

Usage

const {
  collection,
  addItem,
  removeItem,
  setItems,
} = useManageableCollection([]);

useManageableCollection.js

function useManageableCollection(initialValues = []) {
  const [collection, setCollection] = useState(initialValues);

  const addItem = (item) => setCollection([...collection, item]);
  const removeItem = (index) =>
    setCollection(collection.filter((item, testIndex) => index !== testIndex));
  const clearItems = () => setCollection([]);

  return {
    collection,
    addItem,
    removeItem,
    setItems: setCollection,
    clearItems,
  };
}
