Introduction to Hooks: The Start of Intermediate React

This is an intermediate learning course that goes beyond the introductory level of React to focus on the principles and practical applications of Hooks, which are most widely used in real-world development. Through Hooks—the core tools of functional components—you will learn step-by-step how to implement state management, lifecycle control, and performance optimization. In particular, the curriculum is systematically organized to cover everything from basic Hooks like useState and useEffect to the roles and usage patterns of advanced Hooks such as useRef, useMemo, and useCallback, helping you understand which Hook to choose for specific situations. Through hands-on examples, you will go beyond simple coding to gain experience in: - Optimizing state management between components - Preventing unnecessary re-renders - Managing dynamic data and controlling the DOM This will help you develop the intuition needed to solve problems frequently encountered in actual projects. By the end of this course, you will master the Hook-based development workflow—the core of React—and be able to confidently apply it to more complex application structures.
