[] : {}; Object.keys(obj).forEach((key) => { result[key] = deepCopy(obj[key]); }); return result; } export default deepCopy; ``` ## 멘토님과의 회의 - 리팩토링 - 시간 사용에 대한 대가. 비용을 생각해서 수행하기 - 만약 진행한다면 before after에 관한 모습 혹은 수치를 보여줘야함 - 코드에서부터 시작하는 이야기.. - 발표 - 성능 개선 전후 이야기 - flag 처리 이야기(상태 업데이트 시점에 관련한 이야기) - callback 함수 형태로 시점을 다뤄볼까했지만 결국 전달되는 인자들은 업데이트가 되지 않은 인자들 - redux 상태 중 하나로 flag 두기. 처리가 가능은 할 것 같지만 좋은 방법이라는 생각은 들지 않음 + 만약 dispatch가 비동기적으로 처리되는 경우라면? - 차이 전체 (비교하기 / undo / redo) - 체크박스의 역할에 대한 처리방식 ## 성능 측정 시점 1. 새로고침 - 테마 하나 적용된 상태 - 전후 차이가 있는가? - 전 - 41 - 후 - 39/37/47 왔다갔다함.. 2. 비교하기 3. undo/redo 4. 마커의 유무 - 웹팩에서 소스맵 옵션 ## 계획 - profiler를 써서 지금 성능이 어떠한지 파악 - useCallback, useMemo 최적화 가능한 상황들 ( 우리 프로젝트가 최적화되기 힘들다면 왜 그러한지 ) - 성능 측정 도구 - local storage 업데이트 타이밍 관련 수정(멘토님들 적절한 피드백이 있다면) - Map filter expression 수정 - history reset 시 마지막으로 보고있던 버전은 남겨두기 - deepCopy - marker export 시 같은 local storage 공유하는 문제 - init 시 같은 marker들이 중복해서 추가됨 - export한 url에서는 마커 표기만 되고 local storage에 추가하지는 x - 현재 url 참고하면 해결가능할 것 - export한 url 환경에서도 마커추가 가능 - 지도 우클릭시 현재 url이 show 형식이면 마커추가 불가하게 수정 필요
