Function tryCalcDistance

Tries to calculates the distance between two geo coordinates in kilometers. If not enough valid data is submitted, (null) is returned.

Returns

The distance in km or (null) if not enough, valid input data.

Example

const egoCampus = { latitude: 50.78209010114186, longitude: 6.047160498172991 };
const egoFactory = { latitude: 50.7757012931635, longitude: 6.1317278116668605 };

tryCalcDistance(egoCampus, egoFactory)  // 5.988231289819725
tryCalcDistance(egoFactory, egoCampus)  // 5.988231289819725

tryCalcDistance(egoCampus, egoFactory, 'ceil')  // 6
tryCalcDistance(egoCampus, egoFactory, 'floor')  // 5
tryCalcDistance(egoCampus, egoFactory, 'round')  // 6

tryCalcDistance(null, null)  // (null)
tryCalcDistance(undefined, undefined)  // (null)
tryCalcDistance(egoCampus, null)  // (null)
tryCalcDistance(null, egoCampus)  // (null)
tryCalcDistance(egoCampus, undefined)  // (null)
tryCalcDistance(undefined, egoCampus)  // (null)
