Question
I noticed that JavaScript's new Date() function is very smart in accepting
dates in several formats.
Xmas95 = new Date("25 Dec, 1995 23:15:00")
Xmas95 = new Date("2009 06 12,12:52:39")
Xmas95 = new Date("20 09 2006,12:52:39")
I could not find documentation anywhere showing all the valid string formats
while calling new Date() function.
This is for converting a string to a date. If we look at the opposite side, that is, converting a date object to a string, until now I was under the impression that JavaScript doesn't have a built-in API to format a date object into a string.
Editor's note: The following approach is the asker's attempt that worked on a particular browser but does not work in general; see the answers on this page to see some actual solutions.
Today, I played with the toString() method on the date object and
surprisingly it serves the purpose of formatting date to strings.
var d1 = new Date();
d1.toString('yyyy-MM-dd'); //Returns "2009-06-29" in Internet Explorer, but not Firefox or Chrome
d1.toString('dddd, MMMM ,yyyy') //Returns "Monday, June 29,2009" in Internet Explorer, but not Firefox or Chrome
Also here I couldn't find any documentation on all the ways we can format the date object into a string.
Where is the documentation which lists the format specifiers supported by the
Date() object?

I love [10 ways to format time and date using JavaScript](https://www.webdevelopersnotes.com/10-ways-to-format-time-and- date-using-javascript) and Working with Dates.
Basically, you have three methods and you have to combine the strings for yourself:
getDate() // Returns the date
getMonth() // Returns the month
getFullYear() // Returns the year
Example:
var d = new Date();
var curr_date = d.getDate();
var curr_month = d.getMonth() + 1; //Months are zero based
var curr_year = d.getFullYear();
console.log(curr_date + "-" + curr_month + "-" + curr_year);
