Constructors: Date()

What is the purpose of the Date() constructor?

The Date() constructor is used to create Date objects in JavaScript, which represent points in time. Date objects allow you to work with dates and times, including getting the current date and time, manipulating dates, and formatting date and time values.

Example of Using the Date() Constructor

            
// Create a new Date object for the current date and time
const now = new Date()
console.log('Current Date and Time:', now)

Common Methods of Date Objects

getFullYear(): Returns the year of the date.
getMonth(): Returns the month (0-11).
getDate(): Returns the day of the month (1-31).
getHours(): Returns the hour (0-23).
getMinutes(): Returns the minutes (0-59).
getSeconds(): Returns the seconds (0-59).
toString(): Converts the date to a string representation.

Practical Use Case

You can use the Date() constructor to display the current year in a website footer, calculate the difference between two dates, or format dates for display.

            
// Display the current year in the footer
const currentYear = new Date().getFullYear()
document.getElementById('footer').innerText = `© ${currentYear} My Website
