Optimize React performance by applying code-splitting, memoization, and efficient data-fetching patterns. These techniques reduce bundle size and improve render times by loading only necessary code and preventing unnecessary re-renders in your components.

Next.js performance best practices include server/client data strategies, efficient hydration, and strategic code-splitting. These patterns reduce initial load time and improve time-to-interactive by optimizing how data flows and code executes on page load.

Yes. Memoization prevents unnecessary re-renders while code-splitting divides your bundle into smaller chunks loaded on demand. Combined, they significantly reduce both initial load time and runtime performance overhead in React applications.

Apply performance best-practice guidelines during code review to catch common regressions like missing memoization, inefficient data fetching, or avoided code-splitting. Early review prevents performance degradation before changes reach production.

Server-side data strategies fetch and render on the server, reducing client bundle size and improving hydration speed. Client-side strategies fetch in the browser. Choosing correctly based on your use case optimizes load times and user-perceived performance.

Avoid memoization for simple components where re-render cost is negligible, as memoization adds comparison overhead. Use it selectively for expensive components or frequently-re-rendering subtrees to achieve net performance gains without diminishing returns.
