Where should I place this function within the javascript?

const playerManager = (function makePlayerManager() {
function removePlayer() {
videoPlayer.players.forEach(function(player) {
const playerElement = player.getIframe();
if (playerElement) {
const playerClass = playerElement.className;
console.log("Destroying player with class: " + playerClass);
player.destroy();
}
});
console.log("playerRemoved");
}
return {
removePlayer
};
}());

const videoPlayer = (function makeVideoPlayer() {
// videoPlayer code here...
})();

const managePlayer = (function makeManagePlayer() {
// managePlayer code here...
})();

const loadPlayer = (function uiLoadPlayer() {
// loadPlayer code here...
})();

I can do this: Edit fiddle - JSFiddle - Code Playground

function destroyPlayers() {
    videoPlayer.players.forEach(function(player) {
      const playerElement = player.getIframe();
      if (playerElement) {
        const playerClass = playerElement.className;
        console.log("Destroying player with class: " + playerClass);
        player.destroy();
      }
    });
    console.log("playerRemoved");
  }

  return {
    addPlayer,
    destroyPlayers,
    players
  };
}());

function removePlayer() {
    videoPlayer.destroyPlayers();
  }

  function resetPage() {
    hideContainer(".video-containerA");
    showContainer(".modalA");
    removePlayer();
}

or I can do this: Edit fiddle - JSFiddle - Code Playground

const playerManager = (function makePlayerManager() {
  function removePlayer() {
    videoPlayer.players.forEach(function(player) {
      const playerElement = player.getIframe();

        const playerClass = playerElement.className;
        console.log("Destroying player with class: " + playerClass);
        player.destroy();
      }
    });
    console.log("playerRemoved");
  }
  return {
    removePlayer
  };
}());

Are you doing this for web-browser, nodejs or what?

I would write each function on its own file and then import them from there.
