인프런 커뮤니티 질문&답변

아래코드 첨부 하였구요, readAllInfiniteScroll 부분 secondPage 출력 부분에 getParentCommentId 조건 체크 부분에 진입이 되서 그런지, 부모, 하위 댓글 위치가 다르게 출력 됩니다.

강의자료에 있는걸로 이식 해봐도 동일한 증상 나옵니다. 출력 부분은 각 함수마다 하단에 기입 해놨습니다

음 그니까, readAll() 부분은 부모, 자식 구분되서 잘나오는데 무한스크롤 부분에서는 기대값은 아래처럼 첫번째 첨부한 기대값과 같아야 하는데 실제 로직에서 출력되는 부분은 다르게 출력 되는거같습니다. 어떤 부분을 확인 해봐야 할가요??
