+API 통신에 대하여
+
+- 로딩 / 에러 처리를 하는 방법에는 어떤 것들이 있을까?
+  - 로딩:
+    - 로딩 스피너 사용
+    - 사용자에게 메시지 띄우기(ex.로딩중입니다..조금만 기다려주세요 등등)
+  - 에러:
+    - input 에러일때: 사용자에게 메시지 띄우기(ex. 이미 사용중인 아이디입니다)
+    - 에러가 안 뜨는 페이지로 보내고 메시지 띄우기(ex. 일시적 에러가 발생했습니다. 잠시 후 다시 시도해주세요 등등)
+- 패칭 라이브러리란 무엇이고 어떤 것들이 있을까?
+  - "네트워크 요청을 관리하고 처리하기 위한 도구"라고 한다
+  - axios, fetch,..
+  - (사실 자바스크립트에는 fetch api가 존재하지만, 더 많은 기능을 지원하기에 개발자들은 서버 통신에 보다 편리한 axios를 선호한다.라네요)
+- 패칭 라이브러리를 쓰는 이유는 무엇일까?
+  - 1. 간편하다! 이미 필요한 코드들을 응집해서 만들어둔 라이브러리로 그것을 사용하기만 하면 되기 때문에. 비동기처리에도 효과적인 대응이 가능하다
+  - 2. 이건 잘 몰라서 찾아봤는데 인터셉터 및 설정 부분에서 패칭 라이브러리는 요청과 응답을 가로채고 수정할 수 있는 인터셉터를 제공하여 특정 요구사항에 맞게 설정할 수 있다네요..
