Prompt Title: JavaScript Blackjack Example

As an AI language model, I can provide you with an outline of a possible solution for a Blackjack game in JavaScript:

1. Define the deck of cards with an array of card objects, each with a suit, rank, and value.

2. Create a function to shuffle the deck using a random number generator and swapping elements in the array.

3. Define the player and dealer hands as arrays to hold the cards dealt.

4. Create a function to deal the initial two cards to the player and dealer, alternating between the two.

5. Create a function to calculate the total value of a hand by summing the values of the cards. Account for the possibility of an Ace being worth 1 or 11.

6. Create a function for the player to hit, adding a card to their hand.

7. Create a function for the dealer to hit, following a set of rules such as hitting until their hand reaches 17 or above.

8. Create a function to determine the winner by comparing the values of the player and dealer hands.

9. Create a function to reset the game, shuffling the deck and clearing the hands.

Here is some sample code to get you started:

scssCopy code
// Define the deck of cards
const suits = ['Hearts', 'Diamonds', 'Clubs', 'Spades'];
const ranks = ['2', '3', '4', '5', '6', '7', '8', '9', '10', 'Jack', 'Queen', 'King', 'Ace'];

const deck = [];

for (let suit in suits) {
  for (let rank in ranks) {
    let card = {
      suit: suits[suit],
      rank: ranks[rank],
      value: parseInt(rank) + 2
    }
    deck.push(card);
  }
}

// Shuffle the deck
function shuffleDeck() {
  for (let i = deck.length - 1; i > 0; i--) {
    let j = Math.floor(Math.random() * (i + 1));
    [deck[i], deck[j]] = [deck[j], deck[i]];
  }
}

// Define the player and dealer hands
let playerHand = [];
let dealerHand = [];

// Deal the initial two cards
function dealCards() {
  for (let i = 0; i < 2; i++) {
    playerHand.push(deck.pop());
    dealerHand.push(deck.pop());
  }
}

// Calculate the total value of a hand
function calculateHandValue(hand) {
  let total = 0;
  let hasAce = false;
  for (let i = 0; i < hand.length; i++) {
    if (hand[i].rank === 'Ace') {
      hasAce = true;
    }
    total += hand[i].value;
  }
  if (hasAce && total <= 11) {
    total += 10;
  }
  return total;
}

// Player hits
function playerHit() {
  playerHand.push(deck.pop());
}

// Dealer hits
function dealerHit() {
  while (calculateHandValue(dealerHand) < 17) {
    dealerHand.push(deck.pop());
  }
}

// Determine the winner
function determineWinner() {
  let playerValue = calculateHandValue(playerHand);
  let dealerValue = calculateHandValue(dealerHand);
  if (playerValue > 21) {
    return 'Dealer wins';
  } else if (dealerValue > 21) {
    return 'Player wins';
  } else if (playerValue > dealerValue) {
    return 'Player wins';
  } else if (dealerValue > playerValue) {
    return 'Dealer wins';
  } else {
    return 'Tie';
  }
}
