I don't know why I get this strange fomat for this array of objects... Ok let's do it fast: 1 - Convert array in string 2 - Clean up string 3 - Convert string in array

Let's do this... I may also add this... And this... And that... And the other thing there... Then calculate how flat the earth is... But in one line!
