This course goes beyond the React beginner level and is an intermediate learning course that intensively covers the principles and usage of Hooks, which are most frequently utilized in practical development. Through Hooks, the core tool of functional components, you can learn step-by-step how to implement state management, lifecycle control, performance optimization, and more. In particular, it systematically organizes the roles and usage patterns of basic Hooks like useState and useEffect, as well as advanced Hooks such as useRef, useMemo, and useCallback, and is structured to help you understand which Hook to choose for different situations. Through practical examples, you'll go beyond simple code writing to experience: State management optimization between components Prevention of unnecessary rendering Dynamic data management and DOM control This allows you to develop the intuition to solve problems frequently encountered in real projects. Upon completing this course, you'll master Hook-based development flow, which is the core of React, and be able to confidently apply it to more complex application structures.
