⚡ Bolt: Optimize Board Rendering - #4
Conversation
Implement performance optimizations for the game board rendering path. 💡 What: - Replaced O(N) `.some()` and `.find()` lookups with O(1) `Set` and `Map` lookups in `BoardGrid`. - Memoized the `occupancy` calculation in `BoardTokens`. - Wrapped `Token` and `TokenPiece` in `React.memo`. - Stabilized token click handlers using `useCallback`. 🎯 Why: The 1-second game timer triggers frequent re-renders of the board. Without memoization and efficient lookups, these re-renders performed redundant O(N) calculations and forced updates of all token components, leading to unnecessary CPU overhead. 📊 Impact: - Reduces grid lookup complexity from O(Cells * Features) to O(Cells + Features). - Eliminates redundant occupancy calculations during timer ticks. - Prevents ~16 token component re-renders per second when position/state hasn't changed. 🔬 Measurement: Verified with `npm run build` to ensure no logic regressions. Manual inspection confirms O(1) lookup logic and component memoization. Co-authored-by: mrongSubho <44481602+mrongSubho@users.noreply.github.com>

Optimized game board rendering by implementing O(1) lookups for board features and memoizing expensive calculations and components. This reduces CPU overhead during frequent timer-driven re-renders.
