setCachePeriod 메소드에 20으로 설정했다면 브라우저(client) 편 컴퓨터 캐시에 해당 리소스가 20초간 유지되고, 그 후에는 다시 해당 리소스를 요청해서 응답코드가 200이 된다는 건가요? 이것이 아니라면 전후의 차이가 정확히 무엇인지 다시한번 자세한 설명 좀 부탁드립니다..

안녕하세요. 좋은 강의 감사하게 잘 보고있습니다. MemoryMemberRepository에서 Member를 리턴하는 이유가 있는지 궁금합니다. store에 저장만하면 save()의 기능은 끝나는거 아닌가요? 굳이 member를 리턴하는건 왜 그런건가요??

안녕하세요, 강의듣는중 궁금한것이 있어서 질문드립니다. 1) 프롬프트상 바벨로 에러없이 변환 성공했을때, 항상 구버전 브라우저(IE11등)에서 동작하는것을 보장해주나요? ( 휴먼 코드 에러같은 것을 제외하고 ) 2) 1)번과 동일선상에 질문입니다. JQuery, Vue, React의 라이브러리(Component)들을 사용하다보면, 버전업 되면서 점점 "IE11는 더이상 지원 안함"이라고 되어있더라고요,  이런것도 바벨을 돌려서 IE11에서 돌아가게 할 수 있나요??

선생님께선 bottom-up방식이셨네요... 전 처음에풀때 top-down방식으로 한번 해보았습니다. 혹시 이런방식도 가능한지 여쭤보고싶습니다~ def DFS(x,y): if x == n-1: if a[x][y] == 2: print(sp) return else: cnt = 0 a[x][y] = 0 // 갈림길 조정 - 만약에 아래로뻗는 방향밖에없다면 그대로 좌우아래 검색, 만약 아래랑 좌우중 한개가 같이있을경우 무조건 좌우만 검색하게끔 for j in range(3): tx = x+dx[j] ty = y+dy[j] if 0<=tx<n and 0<=ty<n and (a[tx][ty] == 1 or a[tx][ty] == 2): cnt += 1 if cnt == 1: loop = 3 else: loop = 2 for j in range(loop): tx = x+dx[j] ty = y+dy[j] if 0<=tx<n and 0<=ty<n and (a[tx][ty] == 1 or a[tx][ty] == 2): DFS(tx, ty) a[tx][ty] = 1 for z in a: print(z) print() n = 10 a = [ [1,0,1,0,0,1,0,1,0,1], [1,0,1,1,1,1,0,1,0,1], [1,0,1,0,0,1,0,1,0,1], [1,0,1,0,0,1,0,1,1,1], [1,0,1,0,0,1,0,1,0,1], [1,0,1,1,1,1,0,1,0,1], [1,0,1,0,0,1,0,1,1,1], [1,1,1,0,0,1,0,1,0,1], [1,0,1,0,0,1,1,1,0,1], [1,0,1,0,0,2,0,1,0,1] ] dx = [0, 0, 1] dy = [1, -1, 0] sp = 0 for i in range(len(a[0])): if a[0][i] == 1: sp = i print(sp) a[0][i] = 0 DFS(0,i)

굳이 파일을 만들어서 관리하는 이유가 있나요??

선생님 cmd 창과 주피터에서 두번 설치 했더니 이미 설치가 완료 되었다고 뜨고 실행은 안됩니다. 아나콘다도 시도해 보았는데 환경문제로 설치 fail 했다고 뜨네요 어떻게 하면 좋을까요?

배열 데이터 렌더링 및 관리파트에서요. Props로 값 전달 받을 때, PhoneInfo에서는 this.props.info로 받는데요.예) const { name, phone, id }= this.props.info; 왜 PhoneInfoList에서는 그냥 props로만 받는지 궁금합니다.  왜 props.data로 안한 것인가요?예) const {data} = this.props;

안녕하세요~ 선생님! 최근 JPA 를 사용할 일이 생겨 급하게 공부중에 있습니다. 선생님 덕분에 살았어요... ㅎㅎ 다름이 아니라 컬렉션 필드는 선언부에 컬렉션을 객체화하는 것이 베스트 프랙티스고, 이렇게 생성된 객체는 다른 객체로 교체하지 않는 것이 좋다고 하셨는데요. 그렇다면 컬렉션 필드는 final로 선언해도 되는 건가요? 

안녕하세요! 요즘 강사님 강의보면서 스프링에 떨어졌던 정을 다시 붙이고 있는 중입니다. ㅎㅎ 깔끔하고 실무와 연관지어서 설명해주시는 것이 정말 와닿더라구요. 제가 질문을 하는건 다름이 아니고 제가 비전공자로서 독학 중인데 강사님 로드맵 중 어느 것을 먼저 진행해야하나 싶어서입니다. 1. 초급~중급 스프링 완전 정복 2. 초급~활용 스프링 부트와 JPA 완전 정복 로드맵 제 우선 목표는 1번이든 2번이든 완강하고 제 프로젝트를 수행해서 취업하는 것인데 어느 로드맵이 조금이나마 제 상황에 맞을까요? 1번에서 기초를 다지면서 2번으로 실전 능력까지 접하는 것이 베스트일 것 같지만 시간이 한정돼있어서 여쭤봅니다. 바쁘시겠지만 가능한 시간에 답변 부탁드리겠습니다! 감사합니다.

강사님 수업을 듣고 모든 부분을 따라서 만들었습니다.  프로젝트를 보니까 views 라는 곳에 값이 있는데 이게 페이지를 들어 갈때마다 1개씩 증가시키고 싶습니다.. 어떤 함수를 만들어야 할까요?  이렇게 값이 들어있고 페이지에 들어 갔다 나오면  저기서 조회수 부분이 1증가하게 만들고 싶습니다.. 조언 부탁드립니다...

안녕하세요 PDF 파일중 5번은 예제로 구성되어 있더라구요, 이걸 모바일로 옮겼는데 웹페이지 소스를 볼수 있는 방법이 없나요? PC로는 검사나 F12버튼 누르면 소스를 볼수 있는데 모바일은 방법이 없나 해서 질문합니다. 강의 잘 듣겠습니다. 

안녕하세요 좀 사소한 것같은데 질문드립니다. 테스트 코딩시 .end 함수를 기계적으로 쓰고 있는데 혹이 이 의미를 알 수 있을까요?? 너무 사소한 것 같아 죄송하지만 답변부탁드립니다. 감사합니다.
