provide an example for formatdistance from date-fns in javascript

To use formatDistance from date-fns, first, we need to install date-fns as a dependency in our project:

npm install date-fns
21 chars
2 lines

Then, we can import formatDistance from date-fns:

index.tsx
import { formatDistance } from 'date-fns';
43 chars
2 lines

formatDistance function accepts two arguments: start date and end date. It returns a string representing the distance between them.

Here's an example that calculates the distance between two dates:

index.tsx
const startDate = new Date('2021-01-01');
const endDate = new Date('2021-05-01');

const distance = formatDistance(startDate, endDate);

console.log(distance);
// Output: 4 months
180 chars
8 lines

In this example, we pass the two dates: startDate and endDate. The formatDistance function calculates the time difference between them and returns a string that represents the distance (in this case, "4 months").

We can also provide a third argument, options, to customize the output:

index.tsx
const options = {
  addSuffix: true,
  includeSeconds: true
};

const distance = formatDistance(startDate, endDate, options);

console.log(distance);
// Output: in 4 months
173 chars
10 lines

In this updated example, we pass a third argument, options, with two properties: addSuffix and includeSeconds. With addSuffix set to true, the output includes the suffix "in" or "ago". With includeSeconds set to true, the output includes the seconds.
