Date objects are created with the new Date() that represents a single moment in time.
Once a Date object is created, you can allow a number of methods to operate on it.
var dt = new Date();
var dt = new Date(milliseconds);
var dt = new Date(dateString);
var dt = new Date(year, month, day, hours, minutes, seconds, milliseconds);
After creating the instance of the Date object, you can get access all the methods of the object from the “dt” variable.
constructor – Specifies the function that created the Date object’s prototype.
prototype – The property allows to add properties and methods to an object.
This also defines two static methods i.e. Date.parse() and Date.UTC().
This was introduced in Internet Explorer before version 6.
