7 React Mistakes That Still Appear in Production (And How Senior Engineers Avoid Them)

React applications still suffer from common mistakes that lead to performance issues, difficult debugging, and increased maintenance costs. Senior engineers can avoid these pitfalls by understanding and addressing issues like hooks misuse, dependency problems, and state management. To improve code quality, use stable keys when rendering lists, avoid treating useEffect as a replacement for lifecycle methods, and calculate derived values directly during rendering. This can help build and maintain better applications with improved user experiences and scalability.
