# The Complete Guide to React Hooks
React Hooks revolutionized how we write React components. This guide covers all the essential hooks you need to know.
## useState Hook
The most basic hook for managing state:
```javascript
import { useState } from 'react';
function Counter() {
const [count, setCount] = useState(0);
return (
);
}
```
## useEffect Hook
For side effects and lifecycle events:
```javascript
import { useEffect, useState } from 'react';
function DataFetcher() {
const [data, setData] = useState(null);
useEffect(() => {
fetch('/api/data')
.then(response => response.json())
.then(setData);
}, []);
return
Count: {count}
{data ? JSON.stringify(data) : 'Loading...'}
;
}
```
## Custom Hooks
Create reusable logic:
```javascript
function useLocalStorage(key, initialValue) {
const [storedValue, setStoredValue] = useState(() => {
return localStorage.getItem(key) || initialValue;
});
const setValue = (value) => {
setStoredValue(value);
localStorage.setItem(key, value);
};
return [storedValue, setValue];
}
```
