What are some advanced concepts in React 17 hooks?

In React 17, advanced hooks include custom hooks, useReducer for state management, and useContext for global state.

Can you explain how to create a custom hook?

Sure! A custom hook is a JavaScript function that starts with 'use' and can call other hooks. It allows you to extract component logic.

What is the useReducer hook and when should I use it?

The useReducer hook is used for managing complex state logic. It's preferable over useState when you have multiple state values that depend on each other.

How does useContext work with useReducer?

useContext allows you to share state across components without prop drilling. When combined with useReducer, it can manage global state effectively.

Can you give an example of using both together?

Absolutely! You can create a context with useReducer to manage state and provide it to your components, allowing them to access and update the state.
