State example 65

What this example teaches

State

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 State example: import { 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 SaveButton() {.
• Line 4 adds one required part of the working pattern: const [saved, setSaved] = useState(false);.
• Line 5 exposes the output so you can verify the behavior: return <button onClick={() => setSaved(true)}>{saved ? "Saved" : "Save"}</button>;.
• Line 6 adds one required part of the working pattern: }.

Why this example is useful

This example is useful because it isolates state without surrounding noise, so you can see the idea clearly.

Where it is used in real projects

State appears in real React work when a feature needs a clear pattern that can be reviewed and changed safely.
