issue with splicing the deck and displaying

[onesick]

I tried . I expected to happen._____ happened instead.

I tried to splice the deck(52cards) into two 26 cards player hands. But The first player gets length of 26, but the second player's length is 0.

function splitTwo(deck){
  var playerOneHand=deck.splice(0,26);
  var playerTwoHand=deck.splice(26);

  return playerTwoHand;

}

console.log(splitTwo(shuffle()).length);

That's because .splice changes the array on which it's called. For example:

var myArray = [0, 1, 2, 3, 4, 5];
myArray.splice(2, 3);
console.log(myArray);
// this prints [0, 1, 5]

Yes I just fixed it to this, however, only returns one player's hand. Can you please explain why it's doing this?:

function splitTwo(deck){
  var playerOneHand=deck.splice(0,26);
  var playerTwoHand=deck;

  return playerOneHand, playerTwoHand;

}

console.log(splitTwo(shuffle()));

That's because return can only return a single object.

This won't work:

return "hello", "world"

That's trying to return two separate objects.

How could you take two (or more) objects and "package" them inside one object?
