Answer
Techniques include lazy loading, code splitting, memoization (useMemo), pure pipes, virtual DOM optimizations, OnPush change detection, and debouncing/throttling heavy events.
Quick Answer
Framework performance: React.memo / useMemo / useCallback to prevent unnecessary re-renders, code splitting (React.lazy, dynamic imports), virtualized lists for large data, avoid large context re-renders (split contexts), Angular OnPush change detection + trackBy in ngFor, Vue computed properties + v-memo. Profile first — only optimize confirmed bottlenecks.
