Wrapped the StarRating functional component in React.memo to prevent unnecessary re-renders. This optimization is targeted at its usage within list components like BookRow, where parent state changes would previously cause every StarRating instance to re-render, even if its props were unchanged. This improves UI performance by reducing the number of wasted render cycles.
…7328919 ⚡ Bolt: Memoize StarRating component to prevent re-renders
💡 What: Refactored the `TagList` component to use `useMemo` for sorting/filtering tags and wrapped it in `React.memo`. 🎯 Why: The component was performing an O(N*M) lookup and an O(K log K) sort on every render, even when the underlying data hadn't changed. 📊 Impact: Reduces unnecessary re-renders and avoids expensive calculations, especially when used in lists with many items. 🔬 Measurement: Verified with ESLint and code review. Performance gain is theoretical but certain based on React best practices for avoiding O(N*M) work in render. Co-authored-by: Smensink <41000986+Smensink@users.noreply.github.com>

I have optimized the
TagListcomponent by:useMemoto cache the sorted and filtered list of tags. This prevents the O(N*M) search and O(K log K) sort from running on every render unless thetagsortagListchange.React.memoto skip re-rendering entirely when its props are shallowly equal.// ⚡ Bolt:to explain the optimization.These changes follow React best practices for performance in a way that is clean, readable, and safe.
