Blackjack Dealer

This package provides utility functions to simulate a simple card-hand game. It allows you to draw random cards, display the hand's current state, and compute the dealer's hand based on the rules of a basic card game.

Installation

Install the package via npm:

npm install blackjack-dealer

Usage

Here is how you can use the package in your Node.js project:

const { draw, showCard, dealerHand } = require('blackjack-dealer');

// Draw the first card
const firstCard = draw();
console.log(`First card drawn: ${firstCard}`);

// Show the hand
let handValues = [];
showCard(firstCard, handValues);
console.log(`Current hand values: ${handValues}`);

// Compute the dealer's hand
const dealerHandValues = dealerHand(draw, showCard);
console.log(`Dealer's hand values: ${dealerHandValues}`);

API

draw()

Returns a random integer between 1 and 10, representing a card drawn from the deck.

showCard(hand, handValues)

• hand (number): The current value of the hand.
• handValues (array): An array to store the progression of hand values.

Stores the current hand value in the handValues array.

dealerHand(firstCard, showCard)

• firstCard (function): A function that draws a random card.
• showCard (function): A function to display the hand.

Simulates the dealer's hand based on the following rules:

• The dealer starts with two random cards.
• Cards are drawn until the dealer's hand reaches or exceeds 17, or goes bust (>21).
• If the hand value equals 21, it is marked as "Blackjack!".
• If the hand value exceeds 21, it is marked as "Bust!".

Returns an array of hand values, including the final result (e.g., "Blackjack!" or "Bust!").

Example Output

First card drawn: 7
Current hand values: [7]
Dealer's hand values: [14, 19]
