In JavaScript, there are several ways to create a new Date object:
Default Constructor: Creates a new Date object with the current date and time.
let now = new Date();
Date String: Constructs a Date object using a date string.
let dateStr = new Date("2023-12-01");
Date Components: Specifies year, month, and day to create a specific date. The month index starts from 0 (January).
let dateComponents = new Date(2023, 11, 1); // December 1, 2023
Timestamp: Uses a numeric timestamp representing milliseconds since the UNIX epoch (January 1, 1970).
let timestamp = new Date(1670000000000);
Each of these methods offers flexibility in creating Date objects for various requirements in JavaScript programming.
Default Date and Time:
new Date();
This creates a Date object representing the current date and time.
From a Date String:
new Date(dateString);
Constructs a Date object from a specified date string (e.g., “2023-12-01”).
Specifying Date Components:
Year and Month:
new Date(year, month);
Year, Month, and Day:
new Date(year, month, day);
Year, Month, Day, and Hours:
new Date(year, month, day, hours);
Year, Month, Day, Hours, and Minutes:
new Date(year, month, day, hours, minutes);
Year, Month, Day, Hours, Minutes, and Seconds:
new Date(year, month, day, hours, minutes, seconds);
Complete Date with Milliseconds:
new Date(year, month, day, hours, minutes, seconds, ms);
From Milliseconds:
new Date(milliseconds);
Creates a Date object based on the number of milliseconds since January 1, 1970, UTC.
