How do I write this kind of PHP code in Javascript? [duplicate]

I am trying to convert a JSON file to XML using JavaScript. Until now, I used this library : https://github.com/abdolence/x2js ; It does give me the results, but not in the way I want them.

Here's what my JSON looks like :

{
    "data": {
        "key4":{
            "sample8": [
                {
                    "sample9":"val",
                    "sample10":"val"
                },
                {
                    "sample11":"val",
                    "sample12":"val"
                },
                {
                    "sample13":"val",
                    "sample14":"val"
                }
            ]
        }
    }
}

Here's what the XML I get from the library looks like :

<data>
    <key4>
        <sample8>
            <sample9>val</sample9>
            <sample10>val</sample10>
        </sample8>
        <sample8>
            <sample11>val</sample11>
            <sample12>val</sample12>
        </sample8>
        <sample8>
            <sample13>val</sample13>
            <sample14>val</sample14>
        </sample8>
    </key4>
</data>

What I am trying to do is to add <item> ... </item> as element name for every item in JSON array, so my expected end result looks like -

<data>
    <key4>
        <sample8>
            <item>
                <sample9>val</sample9>
                <sample10>val</sample10>
            </item>
            <item>
                <sample11>val</sample11>
                <sample12>val</sample12>
            </item>
            <item>
                <sample13>val</sample13>
                <sample14>val</sample14>
            </item>
        </sample8>
    </key4>
</data>

The following code (in PHP) works perfectly for me, and it adds the <item> as well. -

function toXml($node, $array)
{
  foreach ($array as $key => $value) {
    if (is_array($value)) {
      toXml($node->addChild(is_numeric($key) ? 'item' : $key), $value);
    } else {
      $node->addChild($key, $value);
    }
  }
}

$json = <<<JSON
... my json
JSON;

$jsonArr = json_decode($json, true);
$xml = new SimpleXMLElement('<data/>');

toXml($xml, array_shift($jsonArr));

echo $xml->asXML();

But I am supposed to do this in JS instead of PHP, so I am pretty confused on what should I do... I have read many posts/topics here & on internet, but none of them show how to do something like this; atleast the ones I read... What could be added so I get my desired result? Thanks in advance! :)
