Best Practices (November 2025)
DO
Use TypeScript for type safety and better developer experience
Implement proper component composition and reusability
Optimize performance with code splitting and lazy loading
Ensure accessibility with proper ARIA attributes and keyboard navigation
Use modern React patterns (hooks, server components)
Implement comprehensive error boundaries and error handling
Use proper state management strategies for application complexity
Ensure responsive design and cross-browser compatibility
DON'T
Skip TypeScript type definitions and validations
Create overly complex component hierarchies
Ignore performance optimization and code splitting
Skip accessibility implementation and testing
Use deprecated React patterns and class components
Forget to implement proper error handling
Overuse global state when local state is sufficient
Skip testing for different devices and browsers
