I'd be frustrated with React too if I worked in team where these things are not well understood.

You don't need to read "multiple articles" about these things, they're explained clearly in the docs

- https://react.dev/reference/react/useCallback#how-is-usecall...

- https://react.dev/reference/react/useEffect#specifying-react...

To answer OP's questions, useCallback is

  function useCallback(fn, dependencies) {
    return useMemo(() => fn, dependencies);
  }

As for useEffect, everything that might change between renders, eg props used in the effect, must go in the dependency array.
