You would need to know both the index and the property

function getData(data,index,element){
    console.log(data[index][element]);
}

getData(data,1,"country");

You will need to index into the array still (`data` is an array) - perhaps he should have a parameter specifying the index...? – RB. Feb 01 '17 at 00:20

You are right, I misread the question.**Updated** – Ibu Feb 01 '17 at 00:20

function getData(data,element){
    console.log(data[1][element]);
  }

That's the correct way to access the value by using a key that is a string.
