Answer 1

From the looks of it, it seems that you don't know how to use the "map" method.

Here's a resource that helps you learn more about the "map" method: https://www.w3schools.com/jsref/jsref_map.asp

Here's a fixed version of your code:

Answer 2

The let result at the bottom is what I have tried so far

Answer 3

Thanks, why is is a.country_represented?

Answer 4

Instead of data.

Answer 5

Because the "a" is the object inside the array and I simply accessed the "country_represented" property.

The "map" method lets you loop over an array's elements and it takes a function as an argument.

The first parameter of that function represents the the element inside the array(in this case an object).
