how to use the isfuture function from the date-fns library in typescript

Then, you can import the isFuture function from the date-fns library and use it in your TypeScript code. In this example, we are checking if a given date is in the future:

index.ts
import { isFuture } from 'date-fns';

const myDate: Date = new Date('2022-12-31T23:59:59.999Z');
const isMyDateInFuture: boolean = isFuture(myDate);

console.log(isMyDateInFuture); // true

7 lines

Note that we've used type annotations to specify that the variable myDate should have the Date type in TypeScript. The isFuture function takes a Date object as input and returns a boolean value indicating whether the specified date is in the future.

You can also use the ISO string format to create a Date object:

index.ts
import { isFuture } from 'date-fns';

const myDateString: string = '2022-12-31T23:59:59.999Z';
const myDate: Date = new Date(myDateString);
const isMyDateInFuture: boolean = isFuture(myDate);

console.log(isMyDateInFuture); // true

In this case, we've created a Date object by passing the ISO string format to the constructor.
