Modern React uses functional components with hooks like useState and useEffect instead of class components. This approach organizes logic reusably, improves readability, and simplifies state management within components. The Skill standardizes hook usage patterns for consistency across projects.

React state management depends on complexity: use Context API for simple needs, Redux for large-scale apps, or Zustand for lightweight solutions. The Skill guides you through evaluating options and implementing each pattern with TypeScript, testing, and performance optimization built in.

Performance optimization involves code splitting, lazy loading components, minimizing re-renders with memoization, and tree-shaking unused code. The Skill applies these techniques systematically during development to achieve faster initial load times and smoother runtime performance.

TypeScript catches type errors at development time and improves code maintainability in React projects. The Skill enforces TypeScript usage as a standard practice, generating typed component templates and hooks to reduce bugs and onboarding friction in team environments.

WCAG 2.1 AA compliance requires semantic HTML, ARIA labels, keyboard navigation, and screen reader support. The Skill enforces accessibility conformance during component development and review, helping you build inclusive interfaces that work for all users.

React Testing Library focuses on testing user behavior rather than implementation details, catching real-world bugs. The Skill standardizes testing practices with React Testing Library and TypeScript to ensure reliable components and faster debugging cycles.
