Custom Hooks
Custom Hooks are a React feature that allows developers to extract and reuse stateful logic from components into reusable functions. They enable the sharing of logic across multiple components without changing the component hierarchy, promoting code reusability and separation of concerns. Custom Hooks follow a naming convention starting with 'use' and can call other Hooks like useState or useEffect.
Developers should learn Custom Hooks to avoid code duplication and manage complex state logic in React applications, especially when building large-scale apps with shared functionality like data fetching or form handling. They are essential for creating maintainable and testable code by encapsulating side effects and state management, making components more focused on rendering UI.
