React Hooks were introduced in React 16.8 as a way to add state and other React features to functional components. Hooks are functions that allow developers to use state and lifecycle methods in functional components without needing to write a class component. React Hooks are a powerful tool that can simplify your code, make it more readable, and easier to maintain.
Why Use React Hooks?
Before React Hooks, functional components were limited to only being able to render static data. In order to use state and lifecycle methods in functional components, developers needed to use class components, which have a steeper learning curve and more boilerplate code. With React Hooks, functional components can now have state, perform side effects, and use context, among other things.
Some of the advantages of using React Hooks include:
Hooks simplify your code by allowing you to write functional components instead of class components.
Hooks make your code more readable by grouping related logic together in the same place.
Hooks make your code easier to maintain by reducing the amount of boilerplate and reducing the chance of bugs.
Hooks make it easier to reuse code by allowing you to extract common logic into custom hooks.
The Basic Hooks
React provides a few basic hooks that cover most use cases. The basic hooks include:
useState: Allows you to add state to your functional components.
useEffect: Allows you to perform side effects in your functional components.
useContext: Allows you to use context in your functional components.
useRef: Allows you to create mutable references to elements in your functional components.
These hooks cover most of the use cases for state management, side effects, and context. However, there are also more specialized hooks that can be used for more advanced use cases.
