Sorting according to distance in React

I have a website which allows users to upload a post (like a social media website) made in React.

For each user I have it's latitude and longitude using the Geolocation API.

In the feed of a user, I want to sort the posts according to the location. That means I'll have to do something with the distance between the user and all other users and then sort them.

How do I do that?

Thanks in advance.
