Example usage
async function batchFetch(urls, batchSize) {
  const results = [];
  for (let i = 0; i < urls.length; i += batchSize) {
    const batch = urls.slice(i, i + batchSize).map(url => fetch(url).then(r => r.json()));
    results.push(...(await Promise.all(batch)));
  }
  return results;
}

// Example placeholder (actual usage requires endpoint)
// batchFetch(['/api/1', '/api/2'], 2).then(console.log);
