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

The isThisSecond function from date-fns is used to compare whether the passed-in date object represents this second or not at a given time zone.

Here's an example of how to use the isThisSecond function.

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

const dateObj = new Date('2021-08-24T01:23:45.678Z');
const isThisSecondFlag = isThisSecond(dateObj, { timeZone: 'Asia/Kolkata' });

console.log(isThisSecondFlag);

In the above code, we're requiring the isThisSecond function from the date-fns package. We're then creating a dateObj that represents 2021-08-24T01:23:45.678Z. We're then passing this dateObj and a time zone of Asia/Kolkata to the isThisSecond function. The isThisSecond function returns a boolean flag indicating whether the passed-in date object represents the current second at Asia/Kolkata timezone or not. We're then logging this flag to the console.

Keep in mind that the isThisSecond function checks at second granularity only. Therefore, it is important to pass the appropriate and accurate timezone while using it in your application.
