Example 1: javascript create array of objects from multiple arrays
var ids = [1,2,3];
var names = ["john","doe","foo"];
var countries = ["AU","USA","USA"];
var items = ids.map((id, index) => {
return {
id: id,
name: names[index],
country: countries[index]
}

});
const arrayOfObjhasDuplicates = uniq(arrayOfObjCopy).length != arrayOfObjCopy.length;
