Wrap Up

Congratulations

Congratulations on completing this course! We started by exploring function components, understanding props and the parent/child relationship. We then delved into crafting state variables, unlocking benefits like update requests and responsiveness to value changes. We then discussed React hooks, particularly the useState hook, followed by a detailed look at its application and underlying code structure.

Next, we ventured into side effects, exploring the data structure and code of the useEffect hook. We addressed scenarios for invoking effects and precautions against pitfalls. We discussed performance optimization with an in-depth examination of useMemo, mitigating concerns about web application degradation.

Moreover, we learned about React contexts, revealing their role in facilitating area updates and shared value distribution. We examined the data structure and code behind useContext. We learned how to access DOM elements through refs, showcasing the design and source code of the useRef hook. We also understood how to handle persistent values without dispatch updates.
