## 1. React Router에서 BrowserRouter란 무엇인가요?

**답변**

BrowserRouter는 브라우저의 History API를 사용하여 해시 없는 깔끔한 URL을 생성합니다. URL에 #을 추가하는 HashRouter와 달리, BrowserRouter는 더 나은 사용자 경험과 SEO를 제공합니다. 하지만 프로덕션에서 라우트를 올바르게 처리하려면 서버 설정이 필요합니다.

## 2. React Router에서 라우트를 정의하려면 어떤 컴포넌트를 사용해야 하나요?

**답변**

Route 컴포넌트는 URL 경로와 표시할 컴포넌트 간의 매핑을 정의합니다. 올바르게 작동하려면 Routes 컴포넌트 내부에 배치해야 합니다. 각 Route는 URL이 일치할 때 렌더링할 path와 element를 지정합니다.

## 3. React Router에서 Link 컴포넌트의 목적은 무엇인가요?

**답변**

Link는 페이지를 새로 고침하지 않고 탐색 링크를 생성합니다. 기본 HTML <a> 태그와 달리 Link는 클릭을 가로채고 History API를 사용하여 URL을 변경합니다. 이렇게 하면 애플리케이션 상태가 보존되고 더 빠르고 부드러운 탐색이 제공됩니다.
