Using a Shuffle Function for a Simple Truth or Dare Bot in Discord

Like the title says, I’m using JavaScript to build a Discord bot that just handles picking players in a Truth or Dare game. The bot itself functions fine, but it fails to shuffle the players again at the end of a round.

This is my shuffle function

function shuffle(array) {
    var currentIndex = ping.length -1, temporaryValue, randomIndex
  
    array[0]=0
    while (0 !== currentIndex) {
      array[currentIndex] = currentIndex;
      currentIndex -= 1;
    }

    while (0 !== currentIndex) {  
      
      randomIndex = Math.floor(Math.random() * currentIndex);
      currentIndex -= 1;
       
      temporaryValue = array[currentIndex];
      array[currentIndex] = array[randomIndex];
      array[randomIndex] = temporaryValue;
    }
  
    return array;
      console.log(xrandomindex)
  }

  function shuffleassign(array) {
    var currentIndex = array.length -1, temporaryValue, randomIndex;
  while (0 !== currentIndex) {
    randomIndex = xrandomindex[currentIndex];
    currentIndex -= 1;
    temporaryValue = array[currentIndex];
   array[currentIndex] = array[randomIndex];
    array[randomIndex] = temporaryValue;
}
return array;
}

And here it is in play

else if(message.content.startsWith(`${prefix}n`))    
        if (count > 1)
            {if (countgame == count -1 ) {
              message.channel.send("The queue is being shuffled.")
              shuffle(xrandomindex)
              shuffleassign(ping)
              shuffleassign(users)
              countgame = 0 } 
          message.channel.send ((ping)[countgame] + " is currently asking " + (ping)[countgame + 1] )
          countgame = countgame +1
          msg = count - countgame 
        }
     else message.channel.send("Too few players to start the game.")

function shuffle(array) {
  let currentIndex = array.length, temporaryValue, randomIndex;

  // Continue to shuffle while there are items on the index
  while (0 !== currentIndex) {

    // Pick one of the remaining elements
    randomIndex = Math.floor(Math.random() * currentIndex);
    currentIndex -= 1;

    // Swap it with the current element
    temporaryValue = array[currentIndex];
    array[currentIndex] = array[randomIndex];
    array[randomIndex] = temporaryValue;
  }

  return array;
}

// Used like so
const arr = ['bob', 'billy', 'tom', 'susan'];
shuffle(arr);
console.log(arr);
