shallowEquals에 baseEquals 로직 활용
- baseEuals에 typeGuard 적용
- 순수함수로 로직분리
- useMemo(() => fn, deps)활용 - 함수 자체를 메모이제이션함
훅 역할 - 객체 상태에서 실제 값이 변경되지 않았을 때 리렌더링 방지 - 폼 상태 관리에서 성능 최적화 - 복잡한 객체의 얕은 속성만 관리할 때 사용
역할 - 항상 동일한 함수 참조를 반환

오 이렇게 다 뽑아서 비교하는 로직 엄청 깔끔하고 좋네요!!
다만 isNullish 는 packages/lib/src/equals/baseEquals.ts 에서 2번해서 검사해주니까 여긴 빼도 좋을거같습니다!!
