Usage

The names of the functions have been changed to make them more user friendly. Instead of long winded function names, there is a simple latlng object that can then call easily readable functions getCenter() and getDistance().

New:

import latlng from "latitude-longitude"

latlng.getCenter([[40.739683, 73.985151], [40.730601, 74.000447], [40.742256, 74.006344], [40.691805, 73.908089]])
//=> { lat: 40.72609295152872, lng: 73.97499628519203, zoom: 11 }

latlng.getDistance([40.739683, 73.985151], [40.730601, 74.000447])
//=> 1.6373159082193258

Old (still working):

import { latLngCenter, latLngDistance } from "latitude-longitude"

latLngCenter([[40.739683, 73.985151], [40.730601, 74.000447], [40.742256, 74.006344], [40.691805, 73.908089]])
//=> { lat: 40.72609295152872, lng: 73.97499628519203, zoom: 11 }

latLngDistance([40.739683, 73.985151], [40.730601, 74.000447])
//=> 1.6373159082193258
