Goal of this task is to calculate the distance in kilometers or miles between two given points.

Imagine you have the current location of your browser and a given location , e.g. of a hackerspace: https://raw.githubusercontent.com/fossasia/fossasia-communities/master/Singapore/HackerspaceSG

We now want to know the distance to this hackerspace.

Please write a small script to calculate the distance in javascript. Provide a form on a small web site to demonstrate this function. Find solutions how to calculate the distance, e.g. with the Haversine formula: https://www.wikiwand.com/en/Haversine_formula
