```js
  let foo = {}
  useEffect(() => {
    foo.bar.baz = 43;
  }, []);
```

This asks you to include `foo.bar.baz` into deps. But this doesn't make sense, as you write to it. Instead it should ask to include `foo.bar` into array.

If `foo` is a newly created object in render scope then we might additionally nudge you to `useRef` for it instead. Because otherwise it won't be shared between renders.
const ref1 = useRef();
          const ref2 = useRef();
          useEffect(() => {
            ref1.current.focus();
            console.log(ref2.current.textContent);
            alert(props.someOtherRefs.current.innerHTML);
            fetch(props.color);
          }, [ref1.current, ref2.current, props.someOtherRefs, props.color]);
        }
      `,
