When rendering lists, each item should have a unique key prop for React to track changes efficiently.

import React from 'react';

const ItemList = ({ items }) => {
    return (
        <ul>
            {items.map(item => (
                <li key={item.id}>{item.name}</li>
            ))}
        </ul>
    );
};

const App = () => {
    const items = [
        { id: 1, name: 'Item 1' },
        { id: 2, name: 'Item 2' },
        { id: 3, name: 'Item 3' },
    ];

    return <ItemList items={items} />;
};
