What is the useFetch hook in React?

The useFetch hook is a custom React hook that simplifies data fetching in functional components.

How do I implement the useFetch hook?

You can implement it by creating a function that uses the useState and useEffect hooks to fetch data.

Can you show me a code example?

Sure! Here's a simple example:

import { useState, useEffect } from 'react';

const useFetch = (url) => {
    const [data, setData] = useState(null);
    const [loading, setLoading] = useState(true);

    useEffect(() => {
        const fetchData = async () => {
            const response = await fetch(url);
            const result = await response.json();
            setData(result);
            setLoading(false);
        };
        fetchData();
    }, [url]);

    return { data, loading };
};

You can use this hook in your components to fetch data easily.

Using a custom hook like useFetch promotes code reusability, keeps your components clean, and abstracts the data fetching logic.
