.map

Example 1:

Given a list of countries, write a function that returns an array of strings with the country code and name

Ex:

var countries = [
  {
    "countryCode": "AF",
    "countryName": "Afghanistan",
    "population": "29121286",
    "capital": "Kabul",
    "continentName": "Asia"
  },
  {
    "countryCode": "AL",
    "countryName": "Albania",
    "population": "2986952",
    "capital": "Tirana",
    "continentName": "Europe"
  },
  {
    "countryCode": "DZ",
    "countryName": "Algeria",
    "population": "34586184",
    "capital": "Algiers",
    "continentName": "Africa"
  },
]

explainCodes(countries) // => ["AF stands for Afghanistan","AL stands for Albania","DZ stands for Algeria"]

Example 2:

Write a function that takes the same list of countries, and returns an array of objects with just countryNames, capitals and continentNames.

cleanCountryData(countries)
/*
returns:
[
  {
    "countryName": "Afghanistan",
    "capital": "Kabul",
    "continentName": "Asia"
  },
  {
    "countryName": "Albania",
    "capital": "Tirana",
    "continentName": "Europe"
  },
  {
    "countryName": "Algeria",
    "capital": "Algiers",
    "continentName": "Africa"
  },
]
