In TypeScript, the Date object is used to work with dates and times. It is implemented as a class and provides several methods to work with dates and times. Here are some examples that demonstrate the usage of Date in TypeScript:
1. Creating a new date and time:
const today: Date = new Date(); // current date and time
const christmasDay: Date = new Date(2021, 11, 25); // December 25, 2021
2. Getting the components of a date and time:
const now: Date = new Date();
const year: number = now.getFullYear(); // e.g. 2021
const month: number = now.getMonth(); // e.g. 0 for January, 11 for December
const day: number = now.getDate(); // e.g. 1-31
const hours: number = now.getHours(); // e.g. 0-23
const minutes: number = now.getMinutes(); // e.g. 0-59
const seconds: number = now.getSeconds(); // e.g. 0-59
3. Formatting a date and time:
const today: Date = new Date();
console.log(today.toDateString()); // e.g. "Fri Aug 20 2021"
console.log(today.toLocaleDateString()); // e.g. "8/20/2021"
console.log(today.toLocaleTimeString()); // e.g. "9:30:00 AM"
4. Comparing dates:
const today: Date = new Date();
const tomorrow: Date = new Date(today);
tomorrow.setDate(today.getDate() + 1); // adding one day to today's date
if (today < tomorrow) {
console.log("Tomorrow is after today.");
} else {
console.log("Today is after tomorrow.");
}
These are some basic examples of how to use Date in TypeScript. There are many more methods and options available in the Date class that you can explore in the TypeScript documentation.
