React Programming Tutorials, Guides & Best Practices

This approach drastically reduces the number of rendered DOM nodes, improving performance when dealing with large datasets.

• Avoid unnecessary re-renders: Use React.memo, useMemo, and useCallback to prevent components from re-rendering unnecessarily.
• Use Lazy Loading: Defer loading of components and assets until they are actually needed to improve the initial load time.
• Optimize Large Lists: Use windowing techniques to render only the visible portion of large lists, reducing the rendering workload.
• Profile and Measure: Use React's built-in profiling tools to identify performance bottlenecks and optimize where needed.
