Am I using isNaN() incorrectly? Very strange (Google Ads) Javascript code - always fails in the first execution but succeeds in subsequent tries

The code below is a Google Ads script. It does a fairly simple thing: it grabs the ad group impression share values from any 2 given periods, and issues an alert for ad groups whose impression share values dropped by more than 10% between the "pre" and "post" periods. More details are in the comments in the code.
Here's the really, really weird part: everytime I preview the code (by pressing the "Preview" button in the Google Ads script console), it always fails the first time, but then in subsequent tries (2nd, 3rd, etc) it always works.
If I go back to the Google Ads main "Scripts" page and then open the script and preview it again, it seems to get "reset" and fails again, and then succeeds in the 2nd try onwards.
The exact error is: "TypeError: Cannot read property 'preImpressionShare' of undefined".
According to the Google Ads script console, the line that causes the error is the following:
if ((!isNaN(adgroup.preImpressionShare)))
My questions are:
One would think that if the code is wrong, it should always fail. Yet, it works most of the time, and only fails in the first try. Why is it unstable like that?
How do I fix the error so that it will always work? Is the isNaN() function being used incorrectly or what?

vis.js building a dataset dynamically

I'm working on a project and have a need/desire to use vis.js to display data on a timeline. But, because of how the data is being captured, I need to build the dataset for the timeline somewhat dynamically when the page loads. With that in mind, I started experimenting with ways to do this, but have hit a roadblock that is mostly likely due to my own lack of knowledge.
The following is the test code I've been working with (I'm aware it is not the best or cleanest code. I'm focusing on functionality at the moment, but if you have suggestions for cleaning this up, I'm all ears!) What I want to do is use the content from the variable datasetlist to build the dataset. But when I simply try to pass that variable to new vis.DataSet, it doesn't build the visualization. I'd appreciate any guidance anyone may be able to offer. I was wondering if I needed to transform that variable in some way for vis.js to accept it, but haven't been able to figure out if that is indeed the case, and if so, how.
var ERP = "yes";
var ERPDate = "2018";
var CRM = "no";
var CRMDate = "2019";
var IDSeq = 1;
var datasetlist = "";
var yesCount = 0
//count totalitems
if (ERP == "yes") {
yesCount = (yesCount + 1);
}
if (CRM == "yes") {
yesCount = (yesCount + 1);
}
//builddataset
if (ERP == "yes"){
if (yesCount == IDSeq) {
datasetlist = datasetlist + "{id: " + IDSeq + ", content: \'ERP\', start: \'" + ERPDate + "\'}";
} else {
datasetlist = datasetlist + "{id: " + IDSeq + ", content: \'ERP\', start: \'" + ERPDate + "\'},";
}
IDSeq = IDSeq +1
}
if (CRM == "yes"){
if (yesCount == IDSeq) {
datasetlist = datasetlist + "{id: " + IDSeq + ", content: \'CRM\', start: \'" + CRMDate + "\'}";
} else {
datasetlist = datasetlist + "{id: " + IDSeq + ", content: \'CRM\', start: \'" + CRMDate + "\'},";
}
}
//datasetlist = "{id: 1, content: 'ERP', start: '2018'}"
//window.alert(datasetlist);
// DOM element where the Timeline will be attached
var container = document.getElementById('visualization');
// Create a DataSet (allows two way data-binding)
var items = new vis.DataSet(datasetlist);
// Configuration for the Timeline
var options = {
height: '500px',
start: new Date(2015, 1, 15),
end: new Date(2025, 1, 15),
timeAxis: {scale: 'year', step: 1}
};
// Create a Timeline
var timeline = new vis.Timeline(container, items, options);

Vis expects an array of items as the dataset. Something like this,var data = new vis.DataSet([data]) where [data] is an array of objects. So try building your objects and pushing them into an array and then pass that in as the data parameter. The documentation can be found here http://visjs.org/docs/data/dataset.html.

Javascript How to SetTimeOut while getting a list of files with Scripting.FileSystemObject

This code is for internal, offline, single user use, IE only. The code looks at a folder, and lists all files including those in subfolders. It sorts through the data based on some date fields and datelastmodified. It also uses and if to throw out thumbs.db entries. All of the data is put into a table.
My issue is that this script can take a long time to get the data. I would like to add a progress bar but the progress bar cant update while the script is running. After some research it looks like SetTimeOut can allow the page elements to be updated as the script runs, therefore allowing the progress bar to work and looking overall cleaner. However I can not figure out of to implement SetTimeOut into my existing code.
<script type="text/javascript">
var fso = new ActiveXObject("Scripting.FileSystemObject");
function ShowFolderFileList(folderspec) {
var beginningdate = new Date(startdate.value);
var finishdate = new Date(enddate.value);
var s = "";
var f = fso.GetFolder(folderspec);
var subfolders = new Enumerator(f.SubFolders);
for (subfolders.moveFirst(); !subfolders.atEnd(); subfolders.moveNext()) {
s += ShowFolderFileList(subfolders.item().path);
}
// display all file path names.
var fc = new Enumerator(f.files);
for (i = 0; !fc.atEnd(); fc.moveNext()) {
if (fc.item().name != "Thumbs.db") {
var dateModified = fc.item().DatelastModified;
if (dateModified >= beginningdate && dateModified <= finishdate) {
Date.prototype.toDateString = function () {
return [this.getMonth() + 1, '/', this.getDate(), '/', this.getFullYear()].join('');
}
var dateModifiedClean = (new Date(fc.item().DatelastModified).toDateString());
s += "<table border=0 width=100% cellspacing=0><tr " + ((i % 2) ? "" : "bgcolor=#EBF1DE") + "><td width=75%><font class=find><b>" + fc.item().ParentFolder.name + "</b>" + " - " + fc.item().name + "</font></td><td width=25% align=right><font class=find>" + dateModifiedClean + "</font></td></tr>";
i++;
}
}
}
var results = s + "</table>";
return results;
}
function listFiles() {
outPut.innerHTML = ShowFolderFileList('*Path to scan*');
}
</script>
outPut is the ID of a div tag where the results table is displayed. A button calls the listfiles function.

Merging multiple Google calendar feeds into one JSON object in javascript

I am trying to bring in the JSON feeds from multiple Google calendars so that I can sort the upcoming events and display the next X number in an "Upcoming Events" list.
I have this working with Yahoo! pipes but I want to get away from using a 3rd party to aggregate. I think I am close, but I cannot get the JSON objects created correctly. I am getting the data into the array but not in JSON format, so I can't manipulate it.
I have tried var myJsonString = JSON.stringify(JSONData); using https://github.com/douglascrockford/JSON-js but that just threw errors. I suspect because my variable is in the wrong starting format. I have tried just calling the feed like: $.getJSON(url); and creating a function concant1() to do the JSONData=JSONData.concat(data);, but it doesn't fire and I think it would produce the same end result anyway. I have also tried several other methods of getting the end result I want with varying degrees of doom. Here is the closest I have come so far:
var JSONData = new Array();
var urllist = ["https://www.google.com/calendar/feeds/dg61asqgqg4pust2l20obgdl64%40group.calendar.google.com/public/full?orderby=starttime&max-results=3&sortorder=ascending&futureevents=true&ctz=America/New_York&singleevents=true&alt=json&callback=concant1","https://www.google.com/calendar/feeds/5oc3kvp7lnu5rd4krg2skcu2ng%40group.calendar.google.com/public/full?orderby=starttime&max-results=3&sortorder=ascending&futureevents=true&ctz=America/New_York&singleevents=true&alt=json&callback=concant1","http://www.google.com/calendar/feeds/rine4umu96kl6t46v4fartnho8%40group.calendar.google.com/public/full?orderby=starttime&max-results=3&sortorder=ascending&futureevents=true&ctz=America/New_York&singleevents=true&alt=json&callback=concant1"];
urllist.forEach(function addFeed(url){
alert("The URL being used: "+ url);
if (void 0 != JSONData){JSONData=JSONData.concat($.getJSON(url));}
else{JSONData = $.getJSON(url);}
alert("The count from concantonated JSONData: "+JSONData.length);
});
document.write("The final count from JSONData: "+JSONData.length+"<p>");
console.log(JSONData)
UPDATE:
Now with full working source!! :) If anyone would like to make suggestions on how to improve the code's efficiency it would be gratefully accepted. I hope others find this useful.:

// console.log(urllist[i]);
if (urllist[i] === ""){ urllist.splice(i,1);}
else{
urllist[i] = calPreProperties + urllist[i] + calPostProperties1+maxResults+calPostProperties2;}
}
// console.log("There are " + urllist.length + " URLs");
urllist.forEach(function addFeed(url){
$.getJSON(url, complete);
});
}
else {
errorLog += '<div id="noURLs">No calendars have been selected.</div>';
output();
}
}

All right, here's the gist of what needs to change.
Updated fiddle: http://jsfiddle.net/ynuQ5/2/
Don't concat on the return value of $.getJSON. As I mentioned above, that gets you the XMLHttpRequest object, which is a lot more than the data you're interested in. Critically, however, at that point the request hasn't been made and the data isn't available yet.
Instead, handle it in callback for the AJAX request. I updated your URL list to use &callback=?, initialize the JSONData var to look more like the structure in your 2nd screenshot and then changed the javascript for the AJAX requests to this:
var JSONData = { count: 0,
value : {
description: "Calendars from the Unitarian Universalist Association (UUA.org)",
generator: "StackOverflow communal coding",
items: []
}};
// url list declaration goes here
urllist.forEach(function addFeed(url){
$.getJSON(url, function(result) {
if(!result.feed.entry) {
console.log("No entries from " + url);
return;
}
JSONData.count += result.feed.entry.length;
JSONData.value.items = JSONData.value.items.concat(result.feed.entry);
console.log(JSONData);
});
});
Right away you'll notice there are still some discrepancies between the raw data you get back from google and the data provided by the Yahoo pipe transform. Noticeably, a lot of their provided values have been transformed from objects to texts. For example, google gives us this:
id: Object
$t: "http://www.google.com/calendar/feeds/5oc3kvp7lnu5rd4krg2skcu2ng%40group.calendar.google.com/public/full/bbidp5qb4vh5vk9apok1cpnino_20130119"
link: Array[2]
0: Object
href: "https://www.google.com/calendar/event?eid=YmJpZHA1cWI0dmg1dms5YXBvazFjcG5pbm9fMjAxMzAxMTkgNW9jM2t2cDdsbnU1cmQ0a3JnMnNrY3UybmdAZw"
rel: "alternate"
title: "alternate"
type: "text/html"
1: Object
length: 2
published: Object
$t: "2012-11-13T15:59:31.000-05:00"
title: Object
$t: "30 Days of Love"
type: "text"
updated: Object
$t: "2012-11-13T15:59:31.000-05:00"
Where as your yahoo transform returns data more like this:
id: "http://www.google.com/calendar/feeds/5oc3kvp7lnu5rd4krg2skcu2ng%40group.calendar.google.com/public/full/bbidp5qb4vh5vk9apok1cpnino_20130119"

You can transform the data more when you receive it. Or you can modify your display code to use the more convoluted, raw values.
Let me know if I can clear anything up in my code or response.
Edit: Updated fiddle showing how to access author (aka feed name, apparently), start time and title: http://jsfiddle.net/ynuQ5/8/
Let me know if there's more specific stuff you want out of it :-)

Displaying tweets in my website using my timezone

I am able to display my tweets in my website using the JavaScript below.
window.onload = function() {
var siteName = 'xyz';
$.getJSON(
'http://search.twitter.com/search.json?callback=?&rpp=20&q=from:' + siteName,
function(data) {
$.each(data, function(i, tweets) {
for (var num = 0, len = tweets.length; num < len; num++) {
if (tweets[num].text !== undefined) {
$('ul#tweets').append('<li><b>' + tweets[num].created_at.substring(0, 16) +
':</b> ' + tweets[num].text + '</li>');
}
}
});
}
);
};
This displays the tweets in US time. Is it possible to show the tweets in NZ time.

I found an easy solution to my problem. Just creating a new Date object (var tim = new Date(tweets[num].created_at)) did the trick. Here is the code which give shows date and time of tweets in my timezone.
window.onload = function() {
var siteName = 'xyz';
$.getJSON(
'http://search.twitter.com/search.json?callback=?&rpp=20&q=from:' + siteName,
function(data) {
$.each(data, function(i, tweets) {
for (var num = 0, len = tweets.length; num < len; num++) {
if (tweets[num].text !== undefined) {
var tim = new Date(tweets[num].created_at);
$('ul#tweets').append('<li><b>' + tim.toString().substring(0, 24) + ':</b> ' + tweets[num].text + '</li>');
}
}
});
}
);
};
I think, the var tim = new Data(tweets[num].created_at) constructor is taking the date from tweets[num].created_at and converting it to local timezone (my machine time) and constructing a new object tim. So the new object tim has local time.
Can anyone please point me to the documentation of the Date(dateString) constructor.

Yes. You can change the timezone.
The following js code snippet was found from Twitter's web.
function changetimezone(time_value, tz){
if(!tz){
tz = 0;
}
var values = time_value.split(" ");
time_value = values[1] + " " + values[2] + ", " + values[5] + " " + values[3];
var t = parseInt(Date.parse(time_value))/1000;
return t + tz * 60;
}
So simply parse changetimezone with created_at and your relative timezone.
e.g. changetimezone(tweets[num].created_at,12);
+1200hrs is New Zealand's timezone.
As for what twitter returns, it's actually not US time. It's GMT+0 (London time). So you can safely put 12hrs instead of 20.
