안녕하세요! 로드맵대로 강의를 마치고 이제 실제로 토이 프로젝트를 구현해보고 있습니다. Authorization 헤더에 JWT토큰을 태워서 보내는 형태로 인증을 구현하려고 하는데요. 보통 Spring Security를 사용한다고 나와있어서 해당 라이브러리를 같이 설치한다음 작업하고 있습니다. 관련해서 검색하면서 살펴보고 있는데 제공하는 기능들이 너무나도 많아서 실무에서는 어떤걸 많이 사용하는지 정말 헷갈리네요. 찾아보니 @Secured, @PreAuthorize, @RolesAllowed 라는 3가지의 방법이 존재하는 것 같은데, 실무에서는 어떠한 방법을 사용하나요? (물론 요구사항에 따라 다르겠지만 일반적으로 사용하는걸 알려주시면 제가 검색해서 찾아보겠습니다ㅎㅎ개인적으로는 @PreAuthorize를 사용해서 엔드포인트마다 권한을 세분화하는게 좋다고 생각합니다.)

안녕하세요 선생님 요기까지 강의 끝내고 둘러보는데 flex 된 상품리스트가 다시 수직으로 내려가고 상품상세페이지도 조금 코드가 애러가 난건지 달라져 있더라고요 선생님 코드랑 똑같이 진행했는데 뭔가 코드가 꼬인거 같기도 한데 임시방편이라도 없을까요? 제 추축으론 사진크기 때문이 아닐까 싶어서 선생님 파일 다운받아서 크기 보고 그림판으로 조절 진행한건데 이게 아니라면 바디 쪽 코드를 조정해야하지 않나 조심스레 추측해봅니다.

안녕하세요 캡틴판교님 수업 잘 듣고있습니다. 다름이 아니라 수업에서 chart.js를 추가한거처럼 axios도 한번 추가를 해보려고 사진과 같이 추가를 해봤습니다. 당연히 axios도 설치한 상태입니다. 그런데 위와 같은 에러가 출력됩니다. 찾지를 못한다고 하는대...도무지 왜 못찾는지 이해할 수가 없습니다. 혹시 prototype에 넣을 수 있는 플러그인들이 따로 있는건지 궁금합니다. 감사합니다. :-)

안녕하세요! 텔레메트리 품절로인해 100mw짜리를 구매하여 하고있습니다. 배송이 오늘 드디어 도착했네요 ㅎ 이렇게 보내는대로 출력이 안되고 이상한 문자가 나오는 이유는 뭘까요?

take함수인의 어느 부분인데요 비동기적 상황에서 안전하게 값을 평가 하기 위해서  재귀함수로 처리한 부분입니다. 근데 반복문 부분을 for ..of  로 바꾸니 값이 제대로 나오지 않더라구요 이 코드는 작동을 하는데 이코드는 작동을 하지 않습니다... 왜 그런지 이유를 모르겠습니다... 같은 반복문인데... 왜그런건가요?

 서버 개발에 타입스크립트를 쓰면 자바스크립트를 쓸 때보다 안정적인 서버를 구축할 수 있다는 부분에서 강의 내용과는 크게 관련이 없지만 위의 내용이 궁금해져서요^^;;  실무에서 강타입 언어인 java나 c#같은 정적 언어들로 서버를 개발하는 것보다 동적 언어인 자바스크립트에 타입을 강화하는 타입스크립트를  더해 개발할 때 이점이 무엇인지 궁금합니다.     찾아보니 다양한 의견이 있던데 서버 안정성이 최우선이라면 강타입 언어인 정적 언어로 서버를 구축하는 편이고, 서버의 확장성이 우선이라면 동적 언어를 사용하는 편이라고 이해해도 무리가 없을까요? 참고로 저는 자바스크립트를 첫 개발언어로 배워서 다른 정적언어의 특성들을 잘 모릅니다... 이 부분에 대해서 제로초님은 어떻게 생각하시는지 궁금해서 질문을 올립니다. 

강사님 안녕하세요! plan 섹션을 반응형으로 만드는 과정에서 추가적으로 궁금한 점이 있습니다! history에 div들이 모바일로 바뀌면서 한개씩 슬라이딩하는 형태로 되었는데요. 제가 디자이너로 일할때 이부분 div가 오른쪽에 빼꼼~ 하고 보이는 형태(위 이미지처럼요)가 UX적으로 좋아서 이대로 퍼블에 넘기면 똑같이 해줬었거든요...! 근데 제가 해보려고 혼자서 개발자도구를 열어봤는데  이렇게 클래스 안에 style로 걸려있더라구요. 제가 학원에서(입문정도로만 배워봤습니다) 강사님이 이렇게 클래스에 스타일이 있는건 자바스크립트로 스타일을 준 경우라고 하신 기억이 났습니다. 그래서 slick.min.js에서 이 부분을 찾아서 width를 고쳐보려고 했는데 어떻게 찾아야 할지 모르겠습니다. min으로 되어있어서 보기가 어렵네요!  그래서 responsive.css에 적어서 덮어씌우려고 했는데 이렇게 먹혀버립니다... 어떻게 해야 할까요?

안녕하세요 강사님. 원본데이터에는 공백이 하나인데, split 할때 공백울 2개씩 넣어줘야하는 이유가 있나요? 원본 데이터 '18.17배 l 3,549원' df_pe["PER"] = df_pe['value'].str.split(' l ',expand=True)[0] 제가 복사해서 텍스트 에디터에서 확인하면 공백이 하나입니다. 혹시 복사해서 보면 다르게 보이는건가요? 여기서 공백을 하나만 넣어도 분리는 되지만 다음 결측치 제거에서 공백때문에 공백처리를 한번더 해야합니다.

웹 프론트엔드가 사용자와 상호작용하는 부분이고 웹 백엔드가 네트워크의 응용 프로토콜로 통신하는걸 지원하는거라면 아이피xxx가 할당된 동일한 서버컴퓨터에 웹 프론트와 백엔드가 같이 배포가 되는건가요??? 그리고 사용자 단말기에 설치된 웹 브라우저와 서버컴에 배포되어있는 웹 프론트 코드랑은 어떤 관계가 있나요???

안녕하세요, 선생님! 강의 듣던 중 궁금한 점이 있어서 질문 남깁니다. 원래 텍스트 쓸 때 기본적인 높이값이 있는것 같은데 제가 예제실습 따라하다가 무언가 잘못 설정을 한건지 폰트 크기를 조절해도 폰트 크기 24일때 높이값이 그대로 고정되는데 어떻게 해결해야할까요? - ↑오토레이아웃을 한게 아닌데 위아래로 패딩 먹인 것처럼 간격이 생겨요ㅠ - 이건 다른 파일에서 텍스트 써 본 것입니다. 둘다 폰트는 roboto 체입니다.

안녕하세요 ㅎㅎ 세션과 소켓에 이 정확히 무엇인지 이해가 잘 안돼서 질문드립니다. 제가 이해한걸 정리하면 소캣은 서버와 클라가 통신할 수 있는 수단 혹은 통로라고 생각합니다. 그렇다면 세션은 무엇인가요? 소캣을 포함하며 구조적으로 설계가 잘 된 사용자 정의 인터페이스라고 봐도 되는건가요?

안녕 하세요 좋은 강의 듣고 있습니다. 문의 사항이 있습니다 학습시간을 줄이기 위해서 다음과 같이 하고 있습니다. 1. GPU 3xxx 구입하여 줄림 2.서버를 임대하여 줄임 위의 두 가지 방법은 전부다 이해가 되었는데 만약 1000장을 학습하고 나서  200장을 학습하려고 하면 기존 방법은 1200장을 다시 학습 하였습니다. 200장만 학습하여 시간을 단축 시키는 방법은 없을까요? 답변 부탁 드립니다.
