    upvotes: p.upvotes,
    sentiment: analyzeSentiment(p.title)
  }));
  
  return sentiment;
}

Market Research

async function analyzeTrends(subredditName) {
  const { posts } = await getSubreddit(subredditName);
  
  // Find trending topics
  const topics = {};
  posts.forEach(post => {
    const words = post.title.toLowerCase().split(/\s+/);
    words.forEach(w => {
      if (w.length > 4) topics[w] = (topics[w] || 0) + post.upvotes;
    });
  });
  
  return Object.entries(topics)
    .sort((a, b) => b[1] - a[1])
    .slice(0, 20);
}

Competitor Analysis

async function trackCompetitors(competitors) {
  const mentions = {};
  
  for (const competitor of competitors) {

      totalPosts: results.posts.length,
      totalUpvotes: results.posts.reduce((s, p) => s + p.upvotes, 0),
      sentiment: results.posts.filter(p => p.upvotes > 0).length / results.posts.length
    };
  }
  
  return mentions;
}

Customer Feedback Mining

Extract feedback from relevant subreddits:

async function mineFeedback(subreddits, keywords) {
  const feedback = [];
  
  for (const sub of subreddits) {
    const { posts } = await getSubreddit(sub);

      keywords.some(k => p.title.toLowerCase().includes(k))
    );
    
    for (const post of relevant) {
      const { comments } = await getPostComments(post.url);
      feedback.push({
        post: post.title,
