Comprehensive guide to React component patterns used in the Plataforma B2B de treinamento técnico corporativo educational platform. This skill covers functional components with hooks, composition patterns, state management, props flow, and error handling strategies essential for building maintainable React applications. Learn how to create reusable, testable components following React best practices while avoiding common antipatterns like prop drilling, unnecessary class components, and improper state management. The skill emphasizes composition over inheritance, unidirectional data flow, and separation of concerns. Real-world examples are taken directly from the project codebase, including CLearningSystem, BashLearningSystem, Breadcrumb, AreaCard, and FlashcardModal components. Each pattern is demonstrated with production code showing how architectural decisions were implemented in a 5,500+ line React application with 17 components. Key topics include functional components (vs class components), React Hoo
