Conditional Rendering

• Line 2 adds one required part of the working pattern: const topics = ["Conditional Rendering", "practice", "quiz"];.
• Line 3 exposes the output so you can verify the behavior: return <ul>{topics.map((item) => <li key={item}>{item}</li>)}</ul>;.
• Line 4 adds one required part of the working pattern: }.
