第一个子元素JSON

so I have this json file where I want to get the first child element but don't know how.

$.ajax({
    url: link,
    dataType: 'jsonp',
    success: function (data) {
        if (data.results == null) {
            return;
        }
        deck = data.results.deck;
        publishers = data.results.publishers[0].publisher
    }
//...

it works to get the deck value but not to get the <publisher> in <publishers>
