lastModified returns "Invalid Date"

I'm trying to display the last updated time of a file (not my html file, another file).
HTML:
<p>Last updated: <span id="lastUpdate"></span></p>
JavaScript:
var file = 'data/myFile.csv';
var modifiedTime = new Date(file.lastModified);
document.getElementById('lastUpdate').innerHTML = modifiedTime;
When I run it, it just displays the following; (with no errors in the console)
Last updated: Invalid Date
I'm obviously missing something, probably something small.
Edit:
My files are setup like below:
site/index.html
site/data/myFile.csv
site/js/lastUpdate.js

Yes - when you declare variable
var file = 'data/myFile.csv'
in file variable you have only file path - not file content (to read it you can use fetch). The second thing- when you read file content - then you should parse it - to read proper csv column

How to get producer of a PDF in google app script

I am trying to write a gmail add-on where I iterate over all emails and create a report based on their producers. Iterating over emails is the easiest part and I have done that, however I can't find any way to get producer line of each PDFs.
So far I tried
analyzing the blob, however this is something like writing a PDF library to parse all syntax. producer tag is not clearly present
adding pdf.js, which is a third party open source tool to extract such information. However, I couldn't add it due to ES3 - ES6 support issue.
What's the best way to get the producer line of a PDF in google app script?
Thank you

You want to retrieve the value of Producer from PDF file.
I could understand like above. If my understanding is correct, how about this sample script? In this sample script, from your shared PDF files, the value of Producer is retrieved by 2 regular expressions from the file content. Please think of this as one of several answers.
Sample script:
When you use this script, please set the folder ID of folder that PDF files are put. This script retrieves the value from all PDF files in a folder.
var folderId = "### folderId ###";
var files = DriveApp.getFolderById(folderId).getFilesByType(MimeType.PDF);
var regex = [/Producer\((\w.+)\)/i, /<pdf:Producer>(\w.+)<\/pdf:Producer>/i];
var result = [];
while (files.hasNext()) {
var file = files.next();
var content = file.getBlob().getDataAsString();
var r = regex.reduce(function(s, e) {
var m = content.match(e);
if (Array.isArray(m)) s = m[1];
return s;
}, "");
result.push({
fileName: file.getName(),
fileId: file.getId(),
vaueOfProducer: r,
});
}
Logger.log(result); // Result
Result:
This sample result was retrieved from a folder (my Google Drive) that the shared 3 PDF files were put.
[
{
"fileName": "2348706469653861032.pdf",
"fileId": "###",
"vaueOfProducer": "iText� 7.1.5 �2000-2019 iText Group NV \(iText; licensed version\)"
},
{
"fileName": "Getting started with OneDrive.pdf",
"fileId": "###",
"vaueOfProducer": "Adobe PDF library 15.00"
},
{
"fileName": "DITO-Salesflow-040419-1359-46.pdf",
"fileId": "###",
"vaueOfProducer": "iText 2.1.7 by 1T3XT"
}
]
Note:
About the file of 2348706469653861032.pdf, the characters which cannot be displayed are included in the value of Producer.
This is a sample script. So please modify this for your situation.

Read a file with script

I want to get the content of a file (as string) with google script. It's a txt or html file which I want to edit as string after.
The file is stored on Google Drive and I know the ID.
What I know that you can access the file with:
var Template = DriveApp.getFileById('18DEuu91FJ4rhTYd-xrlNpP2U9jfyheEI');
But I can nothing find how to read the content of this file like "file_get_contents" in PHP.

According to Googles Reference on the Apps Script you can use the getAs() method to return the file contents. I haven't tested this myself, but you could try something like:
var Template = DriveApp.getFileById('18DEuu91FJ4rhTYd-xrlNpP2U9jfyheEI');
var contents = Template.getAs('text/plain');

Get / Read Text File from URL - Javascript for After Effects

I'm used to selecting, opening and reading a text file (CSV, JSON) from my local directory. I now have access to our data feeds online but don't know how to do the same thing with a URL instead of a local file.
For a local file I simply use something like this:
var myFile = File.openDialog();
myFile.open();
myFile.read();
Is there a way to do this with a feed from a URL in javascript for AE?
Here is one of the feeds: feeds.nfl.com/feeds-rs/schedules.json

No need to save file, just one line do the trick =)
data = JSON.parse(system.callSystem('curl -s "https://path_to_json"'));

I think in After Effects the easiest way is to do a system call.
The Socket object from ExtendScript is complicated. Look at GetURLs.jsx by Rorohiko.
You need to allow your script to access the network. See this stackoverflow
# Mac Osx
var curlcmd = "curl feeds.nfl.com/feeds-rs/schedules.json > ~/Desktop/test/schedules.json";
var stdout = system.callSystem(curlcmd);
$.writeln(stdout);
var file = File("~/Desktop/test/schedules.json");
file.open();
var content = file.read();
file.close();
$.writeln(content);

Using Acrobat javascript to write a text file

I am using acrobat XI to write some script. What I would like to do is 1) get the current processed pdf file name and 2) just simply output a text file
var textValue = "test";
var doc = this.createDataObject({cName: "test.txt", cValue: textValue});
this.exportDataObject({cName: "test.txt", nLaunch:0});
This is working , but I would like to provided a fixed path , I tried saveAs but it seems only for pdf , exportAsText not working as well.
Are there any way to fix it? thanks

Official documentation says:
Example: Save the current document in rich text format:
this.saveAs("/c/myDocs/myDoc.rtf", "com.adobe.acrobat.rtf");
I guess you can replace RTF format with TXT (com.adobe.acrobat.plain-text):
this.saveAs("test.txt", "com.adobe.acrobat.plain-text"); // try this
