如何加快获取javascript数组数据的速度

我想获取20000个文件的创建日期并将其存储在数组中。
总完成时间为35分钟，相当长。（）
有没有办法创建处理时间更快的阵列

获取如下文件创建日期数组的当前逻辑是否有问题？
①　数组声明：

var arr=[]

②　我使用以下代码获取文件创建日期：

var fs = global.get('fs');
// Get file creation date time
msg.createdDate = fs.statSync(msg.pathFName).birthtime;
return msg;

③　在数组中存储创建日期。

我的流程：

fs.statSync
，这是一个同步函数，意味着每次调用它时，所有代码执行都会停止，直到该函数完成。请研究使用
fs.stat
（异步版本），映射到文件路径数组，并使用

使用
fs.stat
（异步版本）函数，您可以一次启动多个文件的调用，这样总体上会更快（因为可以一次加载多个文件，而不必等待超慢的文件）

以下是我的意思示例，您可以在浏览器中运行：


const arr=[“你好”、“我”、“是”、“在这里”]；
//这是一个返回承诺的函数示例。
//此函数返回一个承诺，该承诺在'seconds'秒数之后解析，并将'word'的值返回为大写
const sleep和大写=（秒，字）=>新承诺(
（解析）=>设置超时(
（）=>解析（word.toUpperCase（）），秒*1000
)
);
//这包罗了一系列承诺
我保证(
//这会将单词数组转换为上面定义的sleepAndUppercase函数生成的承诺数组
arr.map（（word，i）=>sleep和大写（i，word））
//下一行等待所有promies完成，并将结果用作变量listOfWords，
//这是一个大写的单词数组
).然后（（listOfWords）=>{
//我们可以记录结果
console.log（listOfWords）；
//我们可以根据这些结果创建变量
const语句=listOfWords.join（“”）；
控制台日志（句子）；
});
console.log（“Promissions started”）
感谢您的热情指导，我将尝试使用
fs.stat
