React Hooks Guide

React Hooks allow you to use state and other React features without writing a class component. They are functions that let you "hook into" React state and lifecycle features from functional components.

Common Hooks

useState

useState is the most basic Hook. It lets you add state to functional components.

useEffect

useEffect is used for side effects in functional components. It runs after the component renders.

useContext

useContext allows you to subscribe to React context without introducing nesting.

useReducer

useReducer is a more complex alternative to useState for managing complex state logic.

Best Practices

• Only use Hooks at the top level
• Only use Hooks from React function components
• Use the ESLint plugin to enforce these rules
