💡 What

react-window의 가상화 리스트 아이템 렌더링 내부에 있던 무거운 문자열 Date 파싱(new Date().getTime())을 컴포넌트 렌더링 루프 외부로 분리했습니다.

🎯 Why

스크롤을 빠르게 내릴 때마다 렌더링되는 Row 컴포넌트 내부에서 날짜 문자열 파싱이 불필요하게 반복되어 프레임 드랍이 발생할 수 있는 병목을 해결하기 위함입니다.

📊 Impact

가상화 리스트 렌더링 속도 향상 및 스크롤 시 프레임 드랍 현상 개선

🔬 Measurement

EventList 컴포넌트에서 많은 항목을 렌더링한 후 빠른 스크롤 시 프로파일러 상의 렌더링 지연 및 프레임 드랍 빈도가 낮아졌는지 확인합니다.
