Use React memoization techniques strategically to prevent unnecessary re-renders and recomputations when values change infrequently. Apply React.memo to components that receive stable props, and useMemo for expensive computations that depend on rarely-changing values. Removing memoization can significantly degrade performance by causing excessive re-renders. Conversely, adding memoization to frequently recomputed values that remain stable can provide substantial performance benefits. Example of proper memoization: ```tsx // Memoize component to prevent unnecessary re-renders export const MatchInner = React.memo(function MatchInnerImpl({ matchId, }: { matchId: string }) { // Memoize expensive computation when dependencies are stable const Comp = useMemo(() => route.options.component ?? router.options.defaultComponent, [route.options.component, router.options.defaultComponent] ) return }) ``` Focus memoization efforts on components and computations where the cost of re-execution outweighs the overhead of memoization checks.
