My Favorite React Hooks and Why

React's introduction of hooks has revolutionized functional component development, offering a more intuitive and efficient approach to managing state and side effects.Here are some hooks that have significantly enhanced my development workflow: 1. useState he useState hook allows functional components to manage state variables, eliminating the need for class components.t returns an array with the current state value and a function to update it. ``javascript import { useState } from 'react'; function Counter() { const [count, setCount] = useState(0); return ( Count: {count} setCount(count + 1)}>Increment ); } ` his simplicity makes state management in functional components straightforward and readable. 2. useEffect he useEffect hook enables side effects in functional components, such as data fetching, subscriptions, or manual DOM manipulations.t runs after every render by default, but you can control its execution with dependency arrays. javascript import { useState, useEffect } from 'react'; function DataFetcher() { const [data, setData] = useState(null); useEffect(() => { fetch('https://api.example.com/data') .then(response => response.json()) .then(setData) .catch(console.error); }, []); // Empty array means this effect runs once after the initial render return data ? {JSON.stringify(data)} : Loading...; } ` his hook centralizes side effects, improving component organization and readability. 3. Custom Hooks ustom hooks allow you to extract and reuse component logic, promoting code modularity and maintainability.hey are JavaScript functions that start with "use" and can call other hooks internally. ``javascript import { useState, useEffect } from 'react'; function useWindowWidth() { const [width, setWidth] = useState(window.innerWidth); useEffect(() => { const handleResize = () => setWidth(window.innerWidth); window.addEventListener('resize', handleResize); return () => window.removeEventListener('resize', handleResize); }, []); return width; } y encapsulating specific logic, custom hooks make components cleaner and more focused on their primary responsibilities. astering these hooks has streamlined my React development process, leading to more efficient and maintainable codebases.

React's introduction of hooks has revolutionized functional component development, offering a more intuitive and efficient approach to managing state and side effects.Here are some hooks that have significantly enhanced my development workflow:
1. useState

he useState hook allows functional components to manage state variables, eliminating the need for class components.t returns an array with the current state value and a function to update it.
``javascript
import { useState } from 'react';

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

return (

Count: {count}
setCount(count + 1)}>Increment

);
}
`
his simplicity makes state management in functional components straightforward and readable.
2. useEffect

he useEffect hook enables side effects in functional components, such as data fetching, subscriptions, or manual DOM manipulations.t runs after every render by default, but you can control its execution with dependency arrays.
javascript
import { useState, useEffect } from 'react';

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

useEffect(() => {
fetch('https://api.example.com/data')
.then(response => response.json())
.then(setData)
.catch(console.error);
}, []); // Empty array means this effect runs once after the initial render

return data ? {JSON.stringify(data)} :

Loading...;
}
`
his hook centralizes side effects, improving component organization and readability.
3. Custom Hooks

ustom hooks allow you to extract and reuse component logic, promoting code modularity and maintainability.hey are JavaScript functions that start with "use" and can call other hooks internally.
``javascript
import { useState, useEffect } from 'react';

function useWindowWidth() {
const [width, setWidth] = useState(window.innerWidth);

useEffect(() => {
const handleResize = () => setWidth(window.innerWidth);
window.addEventListener('resize', handleResize);
return () => window.removeEventListener('resize', handleResize);
}, []);

return width;
}



y encapsulating specific logic, custom hooks make components cleaner and more focused on their primary responsibilities.
