Which of the following statements is NOT a valid way to create a date object named birthday?

var birthday = "12/2/1978";

var birthday = new Date ();

var birthday = new Date ("12/2/1978");

var birthday = new Date (1978, 11, 2);

var birthday = "12/2/1978";

Explanation:

It does not create a date object named birthday because in this statement the birthday is a string which contains 12/2/1978 a date it is not date object it is a string. All other three options are correct way to create a date object.

var birthday = new Date ();

creates a date object with the current date and time.

we can also pass date string in the new Date (). So var birthday = new Date ("12/2/1978"); is also correct.

we can also pass year, month, day in new Date () In this order only. So option fourth is also correct.
