Answer 1

It seems unlike the lastModified property, there is no HTML DOM dateCreated property. So if JS needs to access the creation date of a document, it has to access it via the metadata of the file for which it should have access to the file system.

JS not having access to the file system is a security feature in the browsers. But, in-case if someone is wanting to know how to get the creation date for the document for JS as in NodeJS (which of-course has the access to the file-system), then they can use the file system module to get the birthtime property as follows:

const fs = require('fs');

var file = "location-of-my-file";
var dateCreated = fs.statSync(file).birthtime;

console.log("This File was born on:" + dateCreated);

NOTE : The above is only if you are programming a NodeJS app. This will not run on a normal web-browser, and will instead give the following console error : Uncaught ReferenceError: require is not defined.
