递归计算子文件夹中的文件-跟进问题

function countFilesInFolder(folderPath) {
  let count = 0;

  function countFiles(folderPath) {
    const files = fs.readdirSync(folderPath);

    files.forEach((file) => {
      const filePath = path.join(folderPath, file);
      const stats = fs.statSync(filePath);

      if (stats.isFile()) {
        count++;
      } else if (stats.isDirectory()) {
        countFiles(filePath);
      }
    });
  }

  countFiles(folderPath);

  return count;
}

const folderPath = '/path/to/folder';
const fileCount = countFilesInFolder(folderPath);
console.log(`The number of files in ${folderPath} and its subfolders is ${fileCount}.`);
