After a lot of time and a lot of learn & practice I've tried once more and I've found the answer and I can show some example:

const fs = require('fs');

const syncTest = () => {

    const results = [];
    const files = [];

    for (let i=0, len=4; i {
    let startTime = +new Date();
    const results = [];
    const files = [];

    for (let i=0, len=4; i files.push(file));
    };

    for (let i=0, len=360; i
