needs understanding of this format of date and time

I just came across this format of start and end in the codebase which is probably the starting and ending date and time.However, I could not figure out this.
I know how to generate date and time in javascript but I need to generate it in this format to be able to fetch data from API.
Here is the format.

start : '2018-06-20T11:44:21.938Z',
end : '2018-07-20T11:44:21.938Z',


At the same time, I would like to know how to get date and time with exact this format?

var date = new Date(Date.parse('2018-06-20T11:44:21.938Z'));

It's ISO 8601 format.
Check this:
https://en.wikipedia.org/wiki/ISO_8601

It is ISO format of the date. You can use toISOString() method to achieve it:

toISOString()

// current date
var date = new Date();
console.log(date);
console.log(date.toISOString());

let date = new Date( Date.parse('2018-06-20T11:44:21.938Z'));


To retrieve date & time separately.

date.toLocaleDateString();
date.toLocaleTimeString()'


To convert any date object to your desired format (ISO Dates):

var date = new Date();
date.toISOString();


Have a look at toISOString() in MDN

toISOString()

var event = new Date('05 October 2011 14:48 UTC');
console.log(event.toString());
// expected output: Wed Oct 05 2011 16:48:00 GMT+0200 (CEST)
// (note: your timezone may vary)

console.log(event.toISOString());
// expected output: 2011-10-05T14:48:00.000Z


That is the ISO date format.

similar to this:

How do I output an ISO 8601 formatted string in JavaScript?

Here is code to produce it.

function myFunction()
var d = new Date();
var n = d.toISOString();
document.getElementById("demo").innerHTML = n;


<button onclick="myFunction()">convert to ISO date format</button>

<p id="demo"></p>

It is an ISO date. Check this link for some info:
https://www.w3schools.com/js/js_date_formats.asp

var istDate = new Date(); // will return: Wed Sep 05 2018 17:50:39 GMT+0530 (India Standard Time)
var isoDate = istDate.toISOString(); // will return in ISO format i.e. "2018-09-05T12:20:39.732Z"
var dateString = istDate.toDateString(); // will return in format: "Wed Sep 05 2018"

browser console will provide suggestions for various methods of Date Object for extracting day, month, year, etc from the new Date()
