Date Format in JS doesn't work as expected

[Ramonkos]

Formatting dates seem to be not working in the examples of W3 schools. Any ideas why?
 

https://www.w3schools.com/js/js_date_formats

var d = new Date("2015-03-25");

results in:

Wed Mar 25 2015 01:00:00 GMT+0100 (Central European Standard Time)

What is the expected result?

 I assume you want o/p like 2015-0325 only.

So for that, 

You can pull out the parts of a DateTimeFormat one-by-one using DateTimeFormat#format, but note that when using this method, as of March 2020, there is a bug in the ECMAScript implementation when it comes to leading zeros on minutes and seconds .

const d = new Date('2010-08-05')
const ye = new Intl.DateTimeFormat('en', { year: 'numeric' }).format(d)
const mo = new Intl.DateTimeFormat('en', { month: 'short' }).format(d)
const da = new Intl.DateTimeFormat('en', { day: '2-digit' }).format(d)

console.log(`${da}-${mo}-${ye}`)
