In which situations should I use useRef?

Question

I recently read an article entitled You’re overusing useMemo: Rethinking Hooks memoization. In it, I saw something interesting that I hadn’t thought of before, using the useRef to store object references instead of useMemo.

I thought the useRef should be used only to store references of DOM elements. So the questions I have are:

• The useRef really is the most appropriate hook to keep objects reference?

• There is another use case for the useRef?

• How does the behavior of mutable references that are referenced in other Hooks look like useEffect and useCallback?
