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);

JavaScript: how to convert a string to a formatted date?
You can check out the JavaScript Date object. You can create a Date object multiple ways, including passing in the exact string in your question: new Date('1977-04-22');. From there, the Date object has a few built in formatting functions like date.toDateString() which outputs Fri Apr 22 1977. (Be careful though. At the moment, for me it outputs 'Thu Apr 21 1977' since creating the date object with a string defaults to UTC time but the output is in my local timezone). https://css-tricks.com/everything-you-need-to-know-about-date-in-javascript/ and other Google results give more details about how to use the Date object.

May 21, 2020How to create a date object from a string treating the string as local time?
JavaScript Date objects leave something to be desired. For parsing strings like that, you could append the time and timezone to the string for parsing purposes. For example, if I wanted to create today's date in CDT (GMT-5) I could do this: let date = new Date("2022-09-07 00:00:00-05:00"); By appending 00:00:00 I'm specifying a time, and the -05:00 is the timezone. Alternatively, you could create the object with the constructor that accepts year, month, and day: let date2 = new Date(2022, 8, 7) You might notice something odd there, I used 8 for the month instead of 9. That's just how JS handles months (and day of week), as a zero-based number instead of one-based. As to parsing a date string without a specified timezone? I think it will always parse that as UTC.

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());W3Schools
