React hooks are functions that allow developers to use state and lifecycle methods within functional components. Here are the most commonly used hooks in React along with code snippets for each:

  1. useState: This hook is used for managing the state within functional components. It returns an array of two items: the current state value and a function to update that value.

2. useEffect: This hook is used to perform side effects within functional components, such as fetching data from an API or updating the DOM. It takes a function as its argument and runs that function after every render.

Example:

3. useContext: This hook is used for consuming a React context, allowing components to access the global state without the need for props drilling.

Example:

4. useRef: This hook is used for creating a mutable reference that persists between renders. It can be used for storing DOM nodes, creating animations, or implementing custom focus management.

Example:
