"Supercharge Your React Components with Hooks: 10 Must-Know Techniques"

 React Components with Hooks:

Hooks have revolutionized the way we write React components by enabling us to add stateful logic and other features to functional components. In this guide, I'll introduce you to 10 must-know techniques to supercharge your React components with hooks.

1. useState: The useState hook allows you to add state to your functional components. It takes an initial value and returns an array with the current state value and a function to update it. You can use multiple useState hooks to manage different pieces of state within a component.

import React, { useState } from 'react';

function Counter() {

  const [count, setCount] = useState(0);

  return (

    <div>

      <p>Count: {count}</p>

      <button onClick={() => setCount

(count + 1)}>Increment</button>

    </div>

  );

}

2. useEffect: The useEffect hook is used for side effects in your components, such as fetching data, subscribing to events, or updating the document title. It accepts a function that will run after every render. You can also provide a second argument as an array of dependencies to control when the effect runs.

import React, { useState, useEffect }

from 'react';

function DataFetcher() {

  const [data, setData] = useState(null);

  useEffect(() => {

    // Fetch data from an API

    fetch('https://api.example.com/data')

      .then(response => response.json())

      .then(data => setData(data));

  }, []); // Empty dependency array to

run the effect only once

  return (

    <div>

      {data ? <p>Data: {data}</p> :

<p>Loading...</p>}

    </div>

  );

}

3. useContext: The useContext hook allows you to access the value of a context directly within a component, without the need for a context consumer. It accepts a context object created with React.createContext and returns its current value.

import React, { useContext } from 'react';

import UserContext from './UserContext';

function UserProfile() {

  const user = useContext(UserContext);

  return (

    <div>

      <p>Name: {user.name}</p>

      <p>Email: {user.email}</p>

    </div>

  );

}

4. useReducer: The useReducer hook is an alternative to useState when you have complex state logic that involves multiple actions. It takes a reducer function and an initial state and returns the current state and a dispatch function to trigger actions.

import React, { useReducer } from 'react';

function counterReducer(state, action) {

  switch (action.type) {

    case 'INCREMENT':

      return state + 1;

    case 'DECREMENT':

      return state - 1;

    default:

      return state;

  }

}

function Counter() {

  const [count, dispatch] = useReducer

(counterReducer, 0);

  return (

    <div>

      <p>Count: {count}</p>

      <button onClick={() => dispatch({

type: 'INCREMENT' })}>Increment</button>

      <button onClick={() => dispatch({

type: 'DECREMENT' })}>Decrement</button>

    </div>

  );

}

5. useRef: The useRef hook allows you to persist a value across renders without triggering a re-render. It returns a mutable ref object with a .current property. You can use it to access and modify DOM elements or to store any mutable value.

import React, { useRef } from 'react';

function InputWithFocus() {

  const inputRef = useRef(null);

  const focusInput = () => {

    inputRef.current.focus();
