The example code snippets demonstrate the user profiling, recommendation algorithm, user interface, and API integration.

const Watchlist = () => { const [recommendedContent, setRecommendedContent] = useState([]);

return ( <div> <h2>Recommended Content</h2> <ul> {recommendedContent.map((content) => ( <li key={content}>{content}</li> ))} </ul> </div> ); };
