const getQuote = data => {

  // 1) here we are creating the callback function that we will pass to the JSONP request

    delete window[callbackName]

    document.body.removeChild(script)

    callback(data)

  // 2) we are injecting the script tag into our HTML

  script.src =

    url + (url.indexOf('?') >= 0 ? '&' : '?') + 'callback=' + callbackName

/*

Overflow Property in CSS Controls the overflow of one element over another

// If we didn't want it to overflow we can just do this

selector {

    overflow: hidden;

}

function clearBox(elementID)

{

    document.getElementById(elementID).innerHTML = ";

}

//seems like there is no built in funciton's but in jquery 

$(element).empty();

var fs = require('fs');

var path = require('path');

var walk = function(dir, done) {

  var results = [];

  fs.readdir(dir, function(err, list) {

    if (err) return done(err);

    var i = 0;

    (function next() {

      var file = list[i++];

      if (!file) return done(null, results);

      file = path.resolve(dir, file);

      fs.stat(file, function(err, stat) {

        if (stat && stat.isDirectory()) {

          walk(file, function(err, res) {

And to test it out on your home directory (WARNING: the results list will be huge if you have a lot of stuff in your home directory):

walk(process.env.HOME, function(err, results) {

  if (err) throw err;

  console.log(results);

});

function firstFunction(_callback){

    // do some asynchronous work

    // and when the asynchronous stuff is complete

    _callback();    

}

function secondFunction(){

    // call first function and pass in a callback function which

    // first function runs when it has completed

    firstFunction(function() {

        console.log('huzzah, I\'m done!');

    });    

}
