./js/Service/Dir.js

const fs = require( "fs" ),       { join, parse } = require( "path" );  class DirService  {    constructor( dir = null ){     this.dir = dir || process.cwd();   }    static readDir( dir ) {     const fInfoArr = fs.readdirSync( dir, "utf-8" ).map(( fileName ) => {       const filePath = join( dir, fileName ),             stats = DirService.getStats( filePath );       if ( stats === false ) {         return false;       }       return {         fileName,         stats       };     });  return fInfoArr.filter( item => item !== ...
