Prompt Detail:

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:

scss
// 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'; } }
