how to use the addmilliseconds function from date-fns in javascript

The addMilliseconds function from date-fns package in JavaScript can be used to add a specified number of milliseconds to a given date and return a new Date object. Here's an example code snippet:

index.tsx
const { addMilliseconds } = require('date-fns');

const date = new Date('2022-01-01T00:00:00.000Z');
const newDate = addMilliseconds(date, 500); // Adds 500 milliseconds to date

console.log(date.toISOString()); // Output: '2022-01-01T00:00:00.000Z'
console.log(newDate.toISOString()); // Output: '2022-01-01T00:00:00.500Z'

In the above code, new Date() is used to create a date object with the specified date and time. addMilliseconds() is then used to add 500 milliseconds to the date object, which returns a new date object with the updated time. Finally, toISOString() is used to convert the date object to a string in ISO format.
