Splitting a Map instance into two separate arrays

I'm trying to split an instance of Map into separate arrays. An example of the Map instance I have:

new Map([
    ["Guatemala", 7],
    ["Albania", 7],
    ["Finland", 3],
    ["Canada", 12],
    ["Japan", 21],
    ...
]);

There's more data, but just wanted to show a small sample.

I produced it from the raw data I get from an API in JSON format:

[
  {
    id: 1,
    import_country: "Argentina",
    model: "riolet",
    make: "Audi",
    sold_by: "Huey Bagster",
    sale_price: 18643,
  },
  {
    id: 2,
    import_country: "China",
    model: "MKX",
    make: "Lincoln",
    sold_by: "Wolf Coller",
    sale_price: 16850,
  },
  {
    id: 3,
    import_country: "Portugal",
    model: "Coupe Quattro",
    make: "Audi",
    sold_by: "Doroteya McLewd",
    sale_price: 13733,
  },
]

So I took the import_country and counted the number of times it appeared and created map as an instance of Map.

In order to get the keys and values of map in separate arrays, I tried the following:

map.forEach(key, value){
                    country.append(key);
                    numCountry.append(value);
                }

where country and numCountry are separate arrays.

My end desired output is:

country = ["Guatemala", "Albania"...] and 
numCountry = [7, 7, ...]

If your map is an instance of Map, then use its keys and values methods:

const map = new Map([
    ["Guatemala", 7],
    ["Albania", 7],
    ["Finland", 3],
    ["Canada", 12],
    ["Japan", 21],
]);
const countries = [...map.keys()];
const numCountries = [...map.values()];
console.log(countries);
console.log(numCountries);
