Component architecture in scalable apps uses patterns like Presentational and Container separation, Compound components, and Custom Hooks to isolate concerns. This keeps business logic separate from UI rendering, making components reusable and easier to test and maintain across growing codebases.

State management spans local component state, server state, and global state. Frontend patterns guide choosing the right strategy—local state for UI, Provider patterns for shared context, and server-state patterns for API data—balancing complexity with application scale.

WCAG-aligned accessibility integrates ARIA best practices, semantic HTML, and keyboard navigation into component design. Patterns cover focus management, screen reader support, and color contrast within responsive, functional component architectures to ensure inclusive user experiences.

Performance optimization covers rendering efficiency, code splitting, and lazy loading patterns. Techniques like memoization, Higher-Order Components, and Render Props reduce unnecessary re-renders and bundle size, improving load times and runtime responsiveness in complex applications.

Yes, the patterns include TypeScript examples for type-safe component definitions. Functional patterns like Custom Hooks, Provider patterns, and Higher-Order Components all support TypeScript's strict typing, enabling compile-time error detection and better IDE support.

Responsive layout patterns guide building components that adapt across screen sizes using CSS Grid, Flexbox, and media query strategies. Patterns cover mobile-first design, breakpoint management, and component composition techniques for flexible, device-agnostic interfaces.
