Today we'll be going to learn everything about React Hooks and all of its types. This is going to be a fun ride. So, let's keep going.
React Hooks are functions that allow you to use state and other React features in functional components, rather than in class components. They were introduced in React v16.8 in 2019 and since then, it is a recommended way to write React component. They allow you to write more functional and composable code, and make it easier to reuse logic across your application.
React Hooks provide a way to access React features such as state, lifecycle methods, and context, in a functional way, without the need for a class component. They help to make your code more readable, maintainable, and testable.
React provides a set of built-in Hooks that you can use in your functional components to access React features such as state, lifecycle methods, and context. Here's a list of the 15 built-in Hooks in React:
useState
Allows a functional component to use state, similar to how a class component would use this.state.
useEffect
Allows a functional component to use lifecycle methods, such as componentDidMount and componentDidUpdate, in a way that is similar to how they would be used in a class component.
useContext
Allows a functional component to access context, which is a way to pass data through the component tree without having to pass props down manually at every level.
useReducer
Allows a functional component to use a reducer, which is a way to handle complex state changes and updates.
useCallback
A hook that returns a memoized callback. It takes two arguments, the callback function, and an array of dependencies.
useMemo
A hook that returns a memoized value. It takes two arguments, a function that returns the value, and an array of dependencies.
useRef
A hook that returns a ref object which holds a mutable value.
useImperativeHandle
A hook that allows you to customize the instance value that is exposed to parent components when using forwardRef.
useLayoutEffect
Same as useEffect but it runs synchronously after all DOM mutations.
useDebugValue
Allows you to add a label to custom hooks for more meaningful debugging.
useErrorBoundary
Allows you to create an error boundary component, to handle errors that occur during the lifecycle of a component.
useMutationEffect
Same as useEffect but it runs synchronously after all DOM mutations.
useResponder
Allows you to build gesture-based interactions.
useTransition
Allows you to schedule animations and manage the lifecycle of components that are entering, exiting, or updating.
useDeferredValue
A hook that allows you to work with a deferred value, which updates at a lower priority than other state updates.
These are all the built-in hooks that React provides, you can use these hooks to access React features in a functional way, without the need for a class component.
That’s a wrap. Thanks for reading.
