NodeJS practice challenge

This project contains 2 solved questions

Question 1:

Write a function called deepClone which takes an object and creates a copy of it. e.g. {name: "Paddy", address: {town: "Lerum", country: "Sweden"}} -> {name: "Paddy", address: {town: "Lerum", country: "Sweden"}}

Question 2:

We'd like to contact partners with offices within 100km of central London (coordinates 51.515419, -0.141099) to invite them out for a meal.

Write a NodeJS/JavaScript program that reads our list of partners (download partners.json here) and outputs the company names and addresses of matching partners (with offices within 100km) sorted by company name (ascending).

You can use the first formula from this Wikipedia article to calculate distance. Don't forget to convert degrees to radians! Your program should be fully tested too.
