| Criterion | Rating | Notes | |-----------|--------|-------| | | ⭐⭐⭐⭐⭐ | Mosh speaks at a good pace, no "umms" or lengthy digressions. Each video is 5–12 minutes. | | Clear | ⭐⭐⭐⭐⭐ | Visual diagrams of how React renders, how state updates queue, and how the virtual DOM works are excellent. | | Optimized | ⭐⭐⭐⭐ | He covers React.memo , useCallback , and useMemo in a dedicated performance section. However, he could spend more time on when premature optimization harms. | | FCO Only | ⭐⭐⭐⭐⭐ | Zero class components. Zero legacy API mentions. | | React 18 | ⭐⭐⭐⭐ | useTransition and Concurrent features are covered, but some advanced 18 features (like useSyncExternalStore for external stores) are only briefly mentioned. | | | Optimized | ⭐⭐⭐⭐ | He covers React
