The differenceInMinutes function calculates the difference in minutes between two dates or timestamps. It accepts two arguments - the first argument is the date or timestamp to subtract from, and the second argument is the date or timestamp to subtract.

Here's an example code snippet that demonstrates how to use the differenceInMinutes function:

index.tsx
import { differenceInMinutes } from 'date-fns';

const start = new Date(2021, 9, 1, 12, 0);
const end = new Date(2021, 9, 1, 14, 30);

const minutesDiff = differenceInMinutes(end, start);

console.log(`The difference in minutes between ${start} and ${end} is ${minutesDiff}.`)

In the above code, we first created two date objects, representing the start and end times of an event. We then passed these dates to the differenceInMinutes function to calculate the difference in minutes between them. The result is stored in the variable minutesDiff. Finally, we logged the result to the console.
