Date() constructor - JavaScript | MDN
The Date() constructor creates Date objects. When called as a function, it returns a string representing the current time. const date1 = new Date("December 17, 1995 03:24:00"); // Sun Dec 17 1995 03:24:00 GMT... const date2 = new Date("1995-12-17T03:24:00"); // Sun Dec 17 1995 03:24:00 GMT...

The following examples show several ways to create JavaScript dates: Note: Creating a date from a string has a lot of behavior inconsistencies. See date time string format for caveats on using different formats. ... const today = new Date(); const birthday = new Date("December 17, 1995 03:24:00"); // DISCOURAGED: may not work in all runtimes const birthday2 = new Date("1995-12-17T03:24:00"); // This is standardized and will work reliably const birthday3 = new Date(1995, 11, 17); // the month is 0-indexed const birthday4 = new Date(1995, 11, 17, 3, 24, 0); const birthday5 = new Date(628021800000); // passing epoch timestamp

We can always create a date from a timestamp using new Date(timestamp) and convert the existing Date object to a timestamp using the date.getTime() method (see below). Dates before 01.01.1970 have negative timestamps, e.g.: // 31 Dec 1969 let ...

var d = new Date(2011,10,30);
as months are indexed from 0 in js.

You definitely want to use the second expression since months in JS are enumerated from 0.
Also you may use Date.parse method, but it uses different date format:
var timestamp = Date.parse("11/30/2011");
var dateObject = new Date(timestamp);

The best string format for string parsing is the date ISO format together with the JavaScript Date object constructor.
Examples of ISO format: YYYY-MM-DD or YYYY-MM-DDTHH:MM:SS.
But wait! Just using the "ISO format" doesn't work reliably by itself. String are sometimes parsed as UTC and sometimes as localtime (based on browser vendor and version). The best practice should always be to store dates as UTC and make computations as UTC.
To parse a date as UTC, append a Z - e.g.: new Date('2011-04-11T10:20:30Z').
To display a date in UTC, use .toUTCString(),
to display a date in user's local time, use .toString().
More info on MDN | Date and this answer.
For old Internet Explorer compatibility (IE versions less than 9 do not support ISO format in Date constructor), you should split datetime string representation to it's parts and then you can use constructor using datetime parts, e.g.: new Date('2011', '04' - 1, '11', '11', '51', '00'). Note that the number of the month must be 1 less.
Alternate method - use an appropriate library:
You can also take advantage of the library Moment.js that allows parsing date with the specified time zone.

Unfortunately I found out that
var mydate = new Date('2014-04-03');
console.log(mydate.toDateString());returns "Wed Apr 02 2014". I know it sounds crazy, but it happens for some users.
The bulletproof solution is the following:
var parts ='2014-04-03'.split('-');
// Please pay attention to the month (parts[1]); JavaScript counts months from 0:
// January - 0, February - 1, etc.
var mydate = new Date(parts[0], parts[1] - 1, parts[2]);
console.log(mydate.toDateString());GeeksforGeeks

For instance, since the local system time is used to interpret the date, depending upon where in the world your computer is, you could get different results from the same non-specific date. So, when passing a string into new Date(), use a full date with hours:minutes.milliseconds.
