Most Common React Hooks (2024)

Common React Hooks

Here are some of the most commonly used React Hooks:

• useState: Allows you to use state in a functional component.
• useEffect: Allows you to perform side effects in a functional component, such as fetching data from an API or updating the document title.
• useContext: Allows you to use context in a functional component.
• useReducer: Allows you to use a reducer to manage state in a functional component.
• useCallback: Allows you to memoize a function so that it only changes when its dependencies change.
• useMemo: Allows you to memoize a value so that it only changes when its dependencies change.
• useRef: Allows you to create a mutable ref object that persists for the lifetime of the component.

Best practices for using React Hooks

Here are some best practices for using React Hooks:

• Only use React Hooks at the top level of a functional component or custom hook.
• Use the useEffect hook to manage side effects, such as fetching data from an API or updating the document title.
• Use the useCallback hook to memoize functions that are passed as props to child components.
• Use the useMemo hook to memoize values that are expensive to compute.
• Use the useContext hook to pass data down the component tree without having to pass props through every level.
• Use the useReducer hook to manage complex state that can't be managed with the useState hook.

In summary, theReact Hooksare a valuable extension to theReact librarythat enable developers to utilize state and other React features without having to write a class. They offer a means to recyclestateful logicacross different components, streamlining the code-sharing process and minimizing redundancy. By adhering to recommended guidelines when employing React Hooks, you can createReact componentsthat are more effective and easier to manage in the long run.
