How to convert objects of array in to XML in Javascript

container.objects = [];  // init empty array
var i = 1;
while (container["object" + i]) {
    container.objects.push(container["object" + i]);
    i++;
}

container.objects = [{}];  // init array with first item empty as an empty object
var i = 1;
while (container["object" + i]) {
    container.objects.push(container["object" + i]);
    i++;
}

var array = [  
    ['country', 'population'],
    ['someplace', 100],
    ['otherplace', 200]
];

var keys = array.shift();
var objects = array.map(function(values) {
    return keys.reduce(function(o, k, i) {
        o[k] = values[i];
        return o;
    }, {});
});

var arr = [{item: 1}, {item: 2}, {item: 3}];
var obj = {};

for(var i = 0, len = arr.length; i < len; i++){
    obj['item'+i] = arr[i];
}

[{"name": "John"}, {"name": "Alice"}, {"name": "Lily"}]

const normalArray = jsonArray.map(item => {
 const constructedItem = {...item, id: generateRandomID()};

 return constructedItem;
});
