This routine calculates the distance between two points (given the
latitude/longitude of those points). It is being used to calculate
the distance between two locations using GeoDataSource (TM) prodducts.
Passed to function:
lat1, lon1 = Latitude and Longitude of point 1 (in decimal degrees) lat2, lon2 = Latitude and Longitude of point 2 (in decimal degrees) unit = the unit you desire for results
where: 'M' is statute miles (default)
'K' is kilometers

Installation $ npm install biz2credit-calculate-distance-lat-lon

var biz2credit = require('biz2credit-calculate-distance-lat-lon')

  biz2credit.getDistance(lat1, lon1, lat2, lon2, unit);

This routine checks distance is in range or not Passed to function: distance, range
both are in same unit (in KM, M)

var biz2credit = require('biz2credit-calculate-distance-lat-lon')

  biz2credit.isInRange(dist, range); 

This routine is used to sort an object of array on basis on their id Passed to function: arrOfObj = must be array of object or array of number key = key/id of object (their value must be integer type) orderBy = DESC or desc for descending order Asc or asc for ascending order (default)

var biz2credit = require('biz2credit-calculate-distance-lat-lon')

  biz2credit.sortById(arrOfObj, key, orderBy);
