Chapter 11: useRef, useReducer, and Other Essential Hooks

Welcome back, future React pro! In our previous chapters, you mastered the foundational useState for managing simple component state and useEffect for handling side effects. You’ve built interactive components and started to see the power of React’s declarative approach.

But what happens when your state logic gets a bit more involved, or when you need to interact with the raw DOM, or even when you start noticing performance hiccups in larger applications? That’s where a deeper dive into React’s essential hooks comes in!

Chapter 12: Custom Hooks: Reusing Logic Across Components

Welcome back, intrepid React developer! In previous chapters, we’ve explored the fundamental built-in Hooks like useState and useEffect, which revolutionized how we manage state and side effects in functional components. You’ve seen how powerful they are for managing component-specific logic.

But what happens when you find yourself writing the same useState and useEffect logic in multiple components? Perhaps you have several components that all need to fetch data from a similar API endpoint, or they all need to manage a toggle state with similar side effects. Copy-pasting code is a common anti-pattern that leads to “boilerplate” and makes your application harder to maintain.
