Context API example 43

What this example teaches

Context API

Output

The component renders tasks, filters and loading state and updates when state or props change.

Line-by-line explanation

• Line 1 sets up the Context API example: import { useEffect, useState } from "react";.
• Line 2 adds one required part of the working pattern: blank line.
• Line 3 adds one required part of the working pattern: export function OrdersPanel() {.
• Line 4 adds one required part of the working pattern: const [orders, setOrders] = useState([]);.
• Line 5 adds one required part of the working pattern: useEffect(() => { fetch("/api/orders").then((res) => res.json()).then(setOrders); }, []);.
• Line 6 exposes the output so you can verify the behavior: return <p>{orders.length} orders loaded</p>;.

Why this example is useful
