What is JavaScript's default Date format?

What is the name of this format?

Wed Jul 06 2022 14:42:13 GMT-0400 (Eastern Daylight Time)

This format is the default format that is output "Independent of input format" from new Date().

source - https://www.w3schools.com/js/js_date_formats.asp w3schools explains the format but fails to mention what it's called before getting into other ISO format types.

How do you turn a date into that format using Moment.js?

Example: 2022-07-15T00:00:00.000Z or 2015-03-25

console.log(moment(new Date()).toISOString());
// 2022-07-06T19:08:36.670Z

console.log(moment(new Date()).toString());
// Wed Jul 06 2022 15:08:36 GMT-0400

console.log(new Date());
// Wed Jul 06 2022 15:08:36 GMT-0400 (Eastern Daylight Time)

console.log(new Date().toString());
// Wed Jul 06 2022 15:08:36 GMT-0400 (Eastern Daylight Time)

You can see that moment(new Date()).toISOString() and moment(new Date()).toString() DO NOT output that same format as the default JS format.

moment(new Date()).toString() is close, but is still missing the (Eastern Daylight Time) which is part of the default.

What is the name of this format?

It's not ISO, it's a format specified in ECMA-262, read more here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toString

To convert it to ISO use date.toISOString()

Btw. don't use w3schools.com this website has major errors

How do you turn a date into that format using Moment.js?

ISO: moment(new Date()).toISOString()
2015-03-25: moment(new Date()).format('yyyy-MM-dd')
ECMA-262: moment(new Date()).toDate().toString()

P.S. I would consider using a different library as moment.js isn't getting updates anymore, but if you don't have a choice it's fine.

Answer:

`console.log(moment(new Date()).toDate());`

That was way harder to find than it should have been.

console.log(moment(new Date()).toDate());
// Wed Jul 06 2022 15:25:52 GMT-0400 (Eastern Daylight Time)

console.log(new Date());
// Wed Jul 06 2022 15:25:52 GMT-0400 (Eastern Daylight Time)

console.log(new Date().toString());
// Wed Jul 06 2022 15:25:52 GMT-0400 (Eastern Daylight Time)
