This is written 2 different ways, but which way is the correct way?

So, I wrote this code 2 different ways, but which way is it supposed to be written?

Which way makes the most sense?

Code 1 https://jsfiddle.net/mfxht794/1/

  function addEvents(handler) {
    eventHandlers.afterPlayerReady = handler;
    events.afterPlayerReady = new Event("afterPlayerReady");
  }

  function init(options, videos) {
    addEvents(options.afterPlayerReady);
    config.playlist = videos.join();
    loadIframeScript();
    window.onYouTubeIframeAPIReady = onYouTubeIframeAPIReady;
  }

  return {
    addPlayer,
    init,
    play
  };
}());

videoPlayer.init({
  afterPlayerReady: function initCover() {
    manageCover.init(function playVideo() {
      videoPlayer.play();
    });
  }
}, [
  "0dgNc5S8cLI",
  "mnfmQe8Mv1g",
  "CHahce95B1g",
  "2VwsvrPFr9w"
]);

Code 2 https://jsfiddle.net/948nkpto/

function addEvents(handler) {
    eventHandlers.afterPlayerReady = handler;
    events.afterPlayerReady = new Event("afterPlayerReady");
  }

  function init(options) {
    addEvents(options.afterPlayerReady);
    config.playlist = options.videos.join();
    loadIframeScript();
    window.onYouTubeIframeAPIReady = onYouTubeIframeAPIReady;
  }

  return {
    addPlayer,
    init,
    play
  };
}());

videoPlayer.init({
  afterPlayerReady: function initCover() {
    manageCover.init(function playVideo() {
      videoPlayer.play();
    });
  },

  videos: [
    "0dgNc5S8cLI",
    "mnfmQe8Mv1g",
    "CHahce95B1g",
    "2VwsvrPFr9w"
  ]
});
