💡 What:
session-timeline-chart.tsx에서 Recharts에 전달되는chartData를useMemo로 메모이제이션하고, 컴포넌트 렌더링 루프 바깥에서new Date().getTime()문자열 파싱 로직을 미리 계산하도록(pre-parsing) 최적화했습니다. 최적화 의도를 담은 주석도 추가했습니다.🎯 Why: 기존 코드는 Recharts 차트의 상호작용 및 리렌더링 과정 중 발생하는 O(N x M) 중첩 루프 내에서 무거운 Date 생성과
getTime()호출을 반복 실행하여, 데이터가 많아질 경우 심각한 메인 스레드 블로킹과 버벅임(bottleneck)을 유발했습니다.📊 Impact:
data참조(reference)가 메모이제이션되어 불필요한 차트 DOM 재계산 및 렌더링 최소화.🔬 Measurement:
