string이 아닌 키가 들어오면 defaultValue로 인한 오동작은 처리할 방법이 없을 것 같아요..! throw new TypeError만 던지고 try catch는 사용하는 부분에서 처리하거나 string이 아닌 키가 들어올땐 콘솔로 경고를 찍고 기본값을 리턴하는 구조는 어떨까요~?

attributeChangedCallback 으로 처리하니 로직이 굉장히 심플해 지는 것 같네요. 저도 다음에 사용해봐야겠어요!👍

이 부분은 중복으로 사용되고 있는거 같은데 함수화 해서 사용하는건 어떨까요~?

sold-outclass를 추가하여 상태를 변경한다.Description
function형태로 선언되었던App을class로 변환MenuItem을App의 상태에 따라 렌더하도록 변경MenuItem품절 속성 추가Additional
App에서rendermethod를 호출할 때menuList의 모든children을replaceChildren으로 교체하는데, 일부분만 수정이 필요한 경우 어떻게 최적화를 진행할 수 있을까App.js에 집중되는 중menuForm,menuList,menuCount,categoryTitleelement 등을 별도의 컴포넌트로 선언함으로써 책임을 분리하는 방향으로 진행하는게 좋을 듯Demo
