React - The Complete Guide 2032

React has transformed frontend development, and companies worldwide rely on it to build dynamic, performant user interfaces. This course takes you from React fundamentals to advanced patterns used in production applications.

We begin with core concepts: JSX syntax, components, and the component lifecycle. You'll understand React's declarative approach and why it leads to more maintainable code. Props and state management are covered extensively, with emphasis on the mental model that makes React click.

React Hooks are a major focus. You'll master useState, useEffect, useContext, useReducer, useMemo, useCallback, and useRef. Beyond the built-in hooks, you'll learn to create custom hooks that encapsulate reusable logic across components.

State management progresses from local state to Context API for simpler cases, then to Redux and Redux Toolkit for complex applications. You'll understand when each approach is appropriate and how to structure state for scalability.

Routing with React Router v6 covers everything from basic navigation to protected routes, nested layouts, and data loading patterns. We then explore Next.js for server-side rendering, static site generation, and API routes.

Advanced topics include performance optimization, testing with Jest and React Testing Library, TypeScript integration, and authentication patterns. Throughout, you'll build multiple projects: a task manager, e-commerce store, and social media dashboard. Graduate ready to build production React applications with confidence.
