Component architecture patterns like Container/Presentational and Compound Components provide scalable structures for React apps. Container components handle logic and state, presentational components render UI, and compound components share implicit state through children, enabling predictable, reusable component hierarchies across large projects.

Modern state management combines local state for individual components, global state for app-wide data, and server state for backend-sourced data. React ecosystems support this through hooks, context, and patterns that keep state close to where it's used, reducing prop drilling and improving performance.

Accessible components require semantic HTML markup, ARIA attributes where needed, keyboard navigation, and responsive design that adapts to different screen sizes. Compound component patterns and accessibility-first patterns ensure components are usable by all users and devices.

Yes, TypeScript strengthens container/presentational patterns by typing props, state, and component interfaces. This catches errors at development time, documents expected data shapes, and makes refactoring safer across React and Next.js codebases.

Key optimizations include memoizing components to prevent unnecessary re-renders, code splitting to reduce bundle size, lazy loading routes and components, and server-side rendering in Next.js. Combined with proper state organization, these techniques dramatically improve load and interaction performance.
