module.exports = function (directorypath, extention, function(error, arrayofnames) {         var fs = require('fs');         var path = require('path');         var filenamesarray = [];         fs.readdir(directorypath,function (error,list){                 list.foreach(function (file) {                         if (path.extname(file) === '.' + extention) {                                 filenamesarray.push(file);                         }                 });         });         return filenamesarray;         }){         return arrayofnames; }

your problem declaring function inside of function declaration.
