Fullstack Jack Card Game


Steve and Josh are bored and want to play something. They don't want to think too much, so they come up with a simple game:

Write a function called **fullstackJack** and figure out who is going to win.

FullstackJack Rules:

- Each player is dealt the same number of cards
- They flip the card at the top of the deck
- The card with the highest value wins the round and the winning player receives a point
- The two cards used are discarded
- The players continue playing until there are no remaining cards
- The player with the most points at the end wins

Example

***Representing Cards:*** A players hand is stored in an array. Each index is a card value.  The card rank is as follows (from lowest to highest):`'2','3','4','5','6','7','8','9','T','J','Q','K','A'`.  Player hands are passed to the `fullstackJack` function as arguments, as in the examples below:


```
// player1Hand = ['A', '7', '8'];
// player2Hand = ['K', '5', '9'];
fullstackJack(['A', '7', '8'], ['K', '5', '9']);
// --> returns "Player 1 wins 2 to 1!"

- Player1 is dealt ['A','7','8']
- Player2 is dealt  ['K','5','9']
- In first round, Ace beats King and Player1 gets one point.
- In second round, 7 beats 5 and Player1 gets his second point.
- In third round, 9 beats 8 and Player2 gets one point.
- You should return "Player1 wins 2 to 1!"

```

```
fullstackJack(['K', 'Q', 'J'], ['Q', 'K', 'J'])
// --> returns "Tie!"
```



*/


// Write Code Below
function fullstackJack(arr1 , arr2){
  var cardValue = ['2','3','4','5','6','7','8','9','10','J','Q','K','A'];
  var score1 = 0;
  var score2 = 0 ;
  var message; 
  for(var i = 0; i < arr1.length; i++){
    if (cardValue.indexOf(arr1[i]) > cardValue.indexOf(arr2[i])){
      score1 ++;
    } else if (cardValue.indexOf(arr2[i]) > cardValue.indexOf(arr1[i])){
      score2 ++;
    }
  }
  if (score1 > score2){
    message = 'Player 1 wins ' + score1 + ' to ' + score2 + '!';
  } else if (score2 > score1){
    message = 'Player 2 wins ' + score2 + ' to ' + score1 + '!';
  } else {
    message = 'Tie!';
  }
  return message;
}
