프록시를 사용한다면 Zig.useState()를 아예 제거하고 Proxy 내부에 set 핸들러를 정의해서 사용하면 어떨까 하는 생각이 드네용

아하 그것도 좋은 생각이에요!!
이번 미션에서는 그냥 기존 React의 useState와 비슷하게 구현하고 싶어서 (setCount()의 형태로 쓰고 싶어서 ㅎㅅㅎ) 이렇게 두었습니다!!
의견 제시 고마와용 🤩

useState를 구현했어서, 2단계 미션에서는 기존의useState를 Proxy로 받아오도록 수정해보았습니다.Counter컴포넌트에서 더 이상getState()로 직접 호출할 필요는 없지만,state에 Proxy를 적용해주기 위해state를 객체로 만들다보니state.value와 같이 접근해야 하는 문제(?)는 있습니다그래도 새로운 개념을 적용시켜본 것에 의의를... ㅎㅅㅎ
앱은 지난번과 같이 여기서 확인 가능합니다!
