如何从fs.Dirent获取类型？

const fs = require('fs');

const directoryPath = './example-directory';

fs.readdir(directoryPath, { withFileTypes: true }, (err, files) => {
  if (err) {
    console.error(err);
    return;
  }
  files.forEach((file) => {
    fs.stat(`${directoryPath}/${file.name}`, (error, stats) => {
      if (error) {
        console.error(error);
        return;
      }
      if (file.isFile()) {
        console.log(`${file.name} is a file`);
      } else if (file.isDirectory()) {
        console.log(`${file.name} is a directory`);
      } else {
        console.log(`${file.name} is neither a file nor a directory`);
      }
    });
  });
});
