Node.js reads a folder and the information in the folder

var fs = require('fs');

fs.readdir('./', 'utf8', function(err, data) {
    
    
    console.log(data);
    // 获取文件信息
    for (var key in data) {
    
    
        console.log(key);
        fs.stat(data[key], function(err2, data2) {
    
    
            console.log(data2, data[key] + "的信息");
        })
    }

})
