안녕하세요.  make private 채널을 만드려고 하는데 회사 슬랙에선 해당 기능이 없네요. 이게 권한이 없어서 그런걸까요?? 혹시 채널 개설한 이후에 비밀채널로 변경할 수 있는 것도 있을까요?

LoginPage에서 로그인할때 preventDefalut()에서 에러가 나서 구글 확장프로그램에 loginSuccess가 나오질 않습니다. 어떻게 해야하나요?  혹시나해서 주석처리하고 로그인하면 에러는 뜨지 않지만 확장프로그램에는 loginSuccess가 나오질 않습니다. ㅠ typeerror event.preventdefault is not a function

예시에서 정답이 6인데 저는 5가 나오고 점수도 100점이뜨는데 뭐가 잘못된걸까요? 새해부터 강의듣고 문제풀기 시작했는데 기본과 팁들을 꼼꼼히 전수해주셔서 감사합니다!

그동안 강의보면서 에러나도 어찌저찌 잘 넘겼는데 ㅠㅠ 이번 에러는 조금 감이 안오네요 ㅠㅠ writer가 유효하지 않게 넘어가는 건지 ㅠㅠ 이유가 있을까요?

오류 CS1061 'GameObject'에는 'instance'에 대한 정의가 포함되어 있지 않고, 'GameObject' 형식의 첫 번째 인수를 허용하는 액세스 가능한 확장 메서드 'instance'이(가) 없습니다. using 지시문 또는 어셈블리 참조가 있는지 확인하세요. 분명 GameManager에서 instance 변수를 public static으로 선언했는데 말이죠... 무엇이 문제인지 모르겠습니다.

제로초님 깃허브에 _document.js가 업데이트 된 것을 보았는데 <script src="https://polyfill.io/v3/polyfill.min.js?features=es6,es7,es8,es9,NodeList.prototype.forEach&flags=gated" /> 가 빠졌더라구요! 혹시 이부분 생략해도 되는건가요 ?

현재 인강 + 독학 백엔드 취준생입니다  현재 제가 스스로 공부하려고 커리큘럼을 짠 상태인대 괜찮으신지 확인한번 부탁드립니다  1. html , css 2. 자바 , 자바스크립트  기초탄탄 공부 !! mvc sql  db기초개념(mvc를 이용한 data를 화면에 적용하는 과정에서 이론교육을 받았었음) 3. spring과 springBoot 관련하여 위 책 2권을 공부하고코드로 배우는 스프링 웹 프로젝트 ,  코드로 배우는 스프링 부트 웹 프로젝트4. 선생님의 인강 시리즈를 처음부터 끝까지 다 듣고 포트폴리오 준비를 하려고  합니다 이 순서와 커리큘럼에 대해서 그래도 선생님의 인강을 듣고 있으니 관련이 있을거같아 질문드리는대 괜찮을까요?혼자 공부하기 때문에 독학은 항상 내가 맞게 잘하고있는걸까 ? 란 생각이 저를 항상 괴롭히기 때문에 여기서나마 조언듣고싶습니다 목표는 확고한대 불안한 마음때문에 집중이 잘 안되네요

안녕하세요 선생님 저는 학원에서 float을 배울때 자식요소에 float을 주면 부모요소에도 float을 줘야 부모요소가 크기값을 같이 가져간다고 배웠습니다. 근데 여기서는 overflow hidden 을 부모요소에 주시더라고요 혹시 부모요소에 float을 주는거랑 overflow hidden을 주는거랑 차이점이 있을까요??  그리고 overflow hidden이라는 속성에 대해서 한번 정리해주시면 감사하겠습니다!

안녕하세요. [actions 속성을 이용한 로그인 기능 구현과 비동기 처리시 유의할 점] 강의까지 듣고 질문 드립니다. 페이지를 새로고침 하더라도 token 값을 유지할 수 있도록 Cookies를 이용하는 것은 이해를 했습니다. 그런데 인터셉터를 이용해서 HTTP 요청을 하기 전에 token 값을 싣는 과정의 필요성에 대해서 의문이 드는데요. -------- 인터셉터 이용하지 않고 아래와 같이 진행해도 되지 않나요? 1. [store/index.js] Cookies에 있는 token 값을 가져와서 Store에 저장하고 Cookies에 token이 없으면 빈 문자열로 초기화 2. [api/index.js] Store에 저장되어 있는 token 값을 가져와서 axios 인스턴스의 headers Authorization에 설정 -------- 어차피 인터셉터에서도 Store에 저장되어 있는 token값을 가져와서 API를 호출하기 직전에 headers Authorization에 설정하는 것인데  굳이 인터셉터에서 하지 않고 api/index.js 에서 설정해줘도 되지 않을까라는 생각이 듭니다. 감사합니다.
