React Hooks Course – All React Hooks Explained
Welcome to the React Hooks Course, where we will cover all the essential hooks that you need to know for building powerful React applications.
Installation
Before we dive into the hooks, let’s quickly go through the installation steps:
$ npm install react
$ npm install react-dom
Hooks List
-
useState
The
useStatehook allows you to add state to functional components. Using this hook, you can easily manage and update component state. -
useEffect
The
useEffecthook enables you to perform side effects in functional components. It replaces lifecycle methods likecomponentDidMount,componentDidUpdateandcomponentWillUnmount. -
useContext
The
useContexthook allows you to access the value of a context directly in a functional component, without the need for a consumer component. -
useReducer
The
useReducerhook is similar touseState, but it allows for more complex state management. It follows the same principles as Redux for managing global state. -
useCallback
The
useCallbackhook is used to optimize performance by memoizing a function value, not recomputing it unless its dependencies change. -
useMemo
The
useMemohook is similar touseCallback, but it memoizes an expensive computed value, not a function. -
useRef
The
useRefhook allows you to create a mutable reference that persists across re-render cycles. It can be used to access DOM nodes or store any mutable value. -
useLayoutEffect
The
useLayoutEffecthook is similar touseEffect, but it runs synchronously after all DOM mutations so you can safely mutate the DOM. -
useImperativeHandle
The
useImperativeHandlehook allows you to customize the instance value that is exposed to parent components when usingrefforwarding. -
useDebugValue
The
useDebugValuehook is used to display custom labels or values when inspecting hooks in React DevTools.
Hey everyone! A lot of you guys are asking what is the extension that autocompletes stuff in this video. The extension I am using is Github Copilot! I just posted a video going over my favourite VSCODE extensions: https://youtu.be/ZPcrEOHpEnU
Finally got the difference between useMemo and useCallback, thanks!!
Pedro Tech is now in my save list….
Nice tutorial, thanks for the video.
Which VS extension are you using ?
This is really useful, thanks for putting this up!
Clear Man
Thanks a lot ❤🙏🏼
Amazing video. This is the only video which clearly explained hooks to me. Many thanks to you.
Awesome Tutorial. Improve code for Button Click : // Button Listener
const increment = (event) => {
if (event.detail === 1) { // Single Click
setCounter(counter + 1);
} else if (event.detail === 2) { // Double Click
setCounter(counter + 20);
}
console.log(counter);
}
Thanks Sir
