Optimize React and Next.js performance during a code review by applying structured rules across eight categories including bundle size, server-side performance, and eliminating data fetching waterfalls to ensure safe and testable changes.

The best way to eliminate data fetching waterfalls in Next.js is to apply structured best practices that parallelize requests, improving both client-side and server-side performance for faster turnarounds.

Reduce bundle size and re-renders in your React application by implementing specific guidelines for JavaScript efficiency and rendering performance, ensuring predictable behavior and better UX in production.

You need to follow battle-tested advanced patterns to refactor React components for server-side performance, utilizing practical rules and safe migration paths to accelerate improvements across client and server contexts.

Apply advanced patterns to improve Next.js rendering performance when addressing complex bottlenecks in client-side data fetching and JavaScript efficiency, using structured guidance to determine exactly when to implement each rule.
