18. Data & Time

 // In JavaScript, you can work with dates using the built-in Date object. The Date object allows you to create, manipulate, and format dates and times.

// Creating a Date Object:
// -> You can create a new Date object by calling the Date constructor with or without arguments. If no arguments are provided, it will create a Date object representing the current date and time.

// ------------------------------------
// Create a Date object representing the current date and time
const currentDate = new Date();
// console.log(currentDate);

// Create a Date object for a specific date and time (year, month, day, hours, minutes, seconds, milliseconds)
const specificDate = new Date(2023, 6, 25, 12, 30, 0, 0);
// console.log(specificDate);

// ------------------------------------

// ------------------------------------
// Getting Different Parts of the Date:
// You can extract various parts of a Date object, such as the year, month, day, hours, minutes, seconds, etc.
// const date = new Date();

// const year = date.getFullYear();
// const month = date.getMonth(); // Month is 0-based (0: January, 1: February, ..., 11: December)
// const day = date.getDate();
// const hours = date.getHours();
// const minutes = date.getMinutes();
// const seconds = date.getSeconds();
// const milliseconds = date.getMilliseconds();

// console.log(`year:  ${year}`);
// console.log(`month:  ${month}`);
// console.log(`day:  ${day}`);
// console.log(`hours:  ${hours}`);
// console.log(`minutes:  ${minutes}`);
// console.log(`seconds:  ${seconds}`);
// console.log(`milliseconds:  ${milliseconds}`);

// ------------------------------------

// ------------------------------------
// Formatting Dates:
// You can format dates to display them in a more readable format using various methods.

// const date = new Date();

// Convert date to a string representation in different formats
// console.log(date.toDateString()); // Output: Mon Jul 25 2023
// console.log(date.toISOString()); // Output: 2023-07-25T00:00:00.000Z
// console.log(date.toLocaleString()); // Output: 7/25/2023, 12:00:00 AM (based on the user's local timezone)
// ------------------------------------

// ------------------------------------
// Working with Time:
// You can perform operations on dates, such as adding or subtracting time.
const date = new Date();

// Add 1 day to the current date
date.setDate(date.getDate() + 1);

// Subtract 2 hours from the current time
date.setHours(date.getHours() - 2);

console.log(date);
