| useRef는 여러가지 타입으로 사용되는데, 작성해주신 것처럼 초기값과 제네릭이 같으면 MutableRefObject인가 그걸로 추론됩니다. | ||
| MutableRefObject는... 상태 대신에 ref를 사용할 때와 같이 어떤 변수를 담아놓을때 사용하게 되는데요, ref.current = "??" 뭐 이런식으로 current에 들어가는 데이터를 정할 수 있습니다. | ||
| 반면에 RefObject는 current가 readonly입니다. 특정 DOM을 조작하거나 할때는 current를 맘대로 변경하는게 아니고 단순히 참조만 하는거니까는 RefObject가 더욱 적합하지 않을까요?! |

| - 자식에게 forwardRef로 ref를 넘겨줄때, 자식이 부모에게 함수를 넘겨줄 수 있는 훅이다. | ||
| - 사용이 권장되지 않는 훅으로 알고있다. |

제 기억으로 예전 문서에는 쓰지말라고만 나와있고 이유에 대해서는 기재되어있지 않았던 것 같습니다
제 뇌피셜로는 리액트가 단방향 데이터흐름을 지향하기때문에 그것을 거스르는 이 훅을 사용하지 말라고 한게 아닐까 싶습니다...
혹은 이걸 사용함으로써 자식과 부모간의 결합이 강해져서 그런것일수도...?
