What are the best practices for using custom hooks in React?

When using custom hooks in React, it's important to follow a few best practices: 1. Name your hooks with a 'use' prefix, 2. Keep them reusable and focused, 3. Avoid using hooks conditionally, and 4. Document your hooks well.

Can you explain why it's important to avoid using hooks conditionally?

Avoiding conditional hooks is crucial because React relies on the order of hooks to manage state and effects. If hooks are called conditionally, it can lead to unpredictable behavior and bugs.

What are some examples of reusable custom hooks?

Some examples of reusable custom hooks include useFetch for data fetching, useForm for handling form state, and useLocalStorage for managing local storage.

How do I test custom hooks?

You can test custom hooks using libraries like React Testing Library or Enzyme. Create a test component that uses the hook and assert the expected behavior.
