javascript - 为什么 readdirSync 会自动对结果进行排序？

Question

我使用 fs.readdirSync(path) 方法检索数组中的文件名。为什么结果数组中的文件名要排序？

function checkFile() {
    try {
        let imgsFolder = './images/';
        let imgs = fs.readdirSync(imgsFolder);

        fs.statSync(imgsFolder);
        return imgs;
    }

    catch (e) {
        console.log("Folder does not exist.");
        fs.mkdirSync("images/");
        console.log("Folder was created.");
    }
}

checkFile();

例如，文件夹中有以下文件:tts.jpg、array.jpg、man.jpg，但我将它们检索为 array.jpg、man.jpg、tts.jpg.

好吧，如果你阅读 readdir readdirSync 引用的信息方法，出现下面的评论

The order in which filenames are read by successive calls to readdir() depends on the filesystem implementation; it is unlikely that the names will be sorted in any fashion.
