How to generate date in the format of credit/debit card expiry date?

Question

I have a requirement of generating dates in this format 'Thru: 12/20' (like credit/debit card expiry date format). What is the best way of generating date in this format?

new Date().toJSON().slice(0,7).split('-').reverse().join('/')

I got the date in mm/yyyy format but couldn't get the desired result

I don't know what the "best" way is, buy at least, what is _your_ way? Where exactly are you stuck? — Jeremy Thille, Dec 12 '21 at 15:56
@JeremyThille, ```new Date().toJSON().slice(0,7).split('-').reverse().join('/')``` I got the date in mm/yyyy format but couldn't get the desired result — Manu J, Dec 12 '21 at 16:07
But the code you gave outputs '12/2021'. You're nearly there, you want '12/21', right? Just remove the extra '20' — Jeremy Thille, Dec 12 '21 at 16:17
random date is fine , just need the date in this format, removed random from question @LawrenceCherone — Manu J, Dec 12 '21 at 16:20

You can use Intl.DateTimeFormat to generate date in day name and dd/MM format

const options = { weekday: 'short', month: 'numeric', day: 'numeric' };
const result = new Intl.DateTimeFormat('en-GB', options).format(new Date());
console.log(result);

With Moment you can simply do:

const date = moment().format("ddd DD/MM");
console.log("Valid until : " + date);

Thanks. Is there any way to do this using Js only ? – Manu J Dec 12 '21 at 16:22

Let's avoid recommending external libs in 2020+ when the browsers provide `Intl.DateTimeFormat` – anthumchris Dec 12 '21 at 16:33

As with any other JS written by other people, Moment is still JS … but I wouldn't recommend using it today: https://momentjs.com/docs/#/-project-status/ – Quentin Dec 12 '21 at 16:33
I've tried Luxon, I don't like it. It's harder to use than Moment and takes much of the easy syntax away. I think I'll keep using good ol'Moment as long as it works. Or as @AnthumChris said, just use `Intl.DateTimeFormat`. – Jeremy Thille Dec 12 '21 at 16:38
