Is there an alternative approach than using player.h?

Is there a different approach that is more stable and works no matter whether it is j or h or anything else?

Can that part be written a different way in the code?

const iframe = player.h;https://jsfiddle.net/eo8s4zt9/

function onPlayerReady(event) {    player = event.target;    player.setVolume(100);    shufflePlaylist(player);    const iframe = player.h;    iframe.dispatchEvent(events.afterPlayerReady);  }    const iframe = player.h;    const eventHandler = eventHandlers.afterPlayerReady;    iframe.addEventListener("afterPlayerReady", eventHandler);  }

I was trying different things and found this that works.

Instead of using this: const iframe = player.h;

I can do this: https://jsfiddle.net/gobt8xe7/

Is this good?

    const iframe = document.querySelector("iframe");    iframe.dispatchEvent(events.afterPlayerReady);  }    const iframe = document.querySelector("iframe");    const eventHandler = eventHandlers.afterPlayerReady;    iframe.addEventListener("afterPlayerReady", eventHandler);  }

Improving on that I can then do this: https://jsfiddle.net/z1kywacL/

function getIframe() {    return document.querySelector("iframe");  }  function shufflePlaylist(player) {    player.setShuffle(true);    player.playVideoAt(0);    player.stopVideo();  }  function onPlayerReady(event) {    player = event.target;    player.setVolume(100);    shufflePlaylist(player);    const iframe = getIframe();    iframe.dispatchEvent(events.afterPlayerReady);  }  function addPlayer(video) {    const playlist = "0dgNc5S8cLI,mnfmQe8Mv1g,-Xgi_way56U,CHahce95B1g";    const config = {      height: 360,      host: "https://www.youtube-nocookie.com",      width: 640    };    config.playerVars = {      autoplay: 0,      cc_load_policy: 0,      controls: 1,      disablekb: 1,      fs: 0,      iv_load_policy: 3,      loop: 1,      playlist,      rel: 0    };    config.events = {"onReady": onPlayerReady    };    player = new YT.Player(video, config);    const iframe = getIframe();    const eventHandler = eventHandlers.afterPlayerReady;    iframe.addEventListener("afterPlayerReady", eventHandler);  }
