Javascript function 返回数组为空

Question

When I use the getAll() I am returned with an empty table. I'm pretty sure its skipping everything inbetween the let filesdir = [] and return filesdir because after I push the files I have used console.log and it has logged the files, but I'm not sure why its completely skipping it
(Image of the directory, I havn't added https to it yet since I havn't bothered to look how to with cloudflare's ssl certifcate)

getAll = async function (directory) {
    let filesdir = [];
    await fs.readdir(directory, async (err, files) => {
        if (err) throw err;
        for (i = 0; i < files.length; i++) {
            var file = files[i];
            //console.log(file)
            var filePath = directory;
            if (await fs.lstatSync(path.join(directory, file)).isFile()) {
                filesdir.push('/' + file);
            } else if (await fs.lstatSync(path.join(directory, file)).isFile()) {
                var dd = getAll(path.join(filePath, file));
                dd.then(function (ee) {
                    for (b = 0; b < ee.length; b++) {
                        filesdir.push('/' + ee[b]);
                    }
                });
            }
        }
    });
    return filesdir;
};

getAll(pathDir).then(function (ee) {
    console.log(ee);
    for (i = 0; i < ee.length; i++) {
        console.log(ee[i]);
    }
});

var fs = require('fs');
var path = require('path');

getAll = async function (directory) {
    let filesdir = [];
    var files = fs.readdirSync(directory);

    for (i = 0; i < files.length; i++) {
        var file = files[i];
        var filePath = directory;
        if (await fs.lstatSync(path.join(directory, file)).isFile()) {
            filesdir.push('/' + file);
        } else if (await fs.lstatSync(path.join(directory, file)).isFile()) {
            var dd = getAll(path.join(filePath, file));
            dd.then(function (ee) {
                for (b = 0; b < ee.length; b++) {
                    filesdir.push('/' + ee[b]);
                }
            });
        }
    }

    return filesdir;
};


getAll('./').then(function (ee) {
    console.log(ee);
    for (i = 0; i < ee.length; i++) {
        console.log(ee[i]);
    }
});
// Or
var ee = await getAll('./');
for (i = 0; i < ee.length; i++) {
    console.log(ee[i]);
}
