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

To use the differenceInSeconds function from the date-fns library in TypeScript, you need to first install the date-fns library and then import the differenceInSeconds function in your TypeScript file.

Here's an example code snippet that shows how to use the differenceInSeconds function from the date-fns library in TypeScript:

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

const date1 = new Date('2021-06-01T00:00:00Z');
const date2 = new Date('2021-06-01T01:30:00Z');

const difference = differenceInSeconds(date2, date1);

console.log(`The difference in seconds between ${date1} and ${date2} is ${difference} seconds.`);

In this code snippet, we import the differenceInSeconds function from the date-fns library. Then we create two Date objects date1 and date2. We then call the differenceInSeconds function and pass in the two Date objects as arguments to get the difference in seconds between the two dates. Finally, we log the difference in seconds to the console.
