API

Dealer Class

Dealer() takes a deck of cards to use for a game & places it on the draw pile.

const dealer = new Dealer(standardDeck);

Shuffle

Randomizes the dealer's draw pile order using the Fisher-Yates shuffle algorithm.

dealer.shuffle(); // Deck is now randomized 

Cut Deck

Cuts the deck at the specified position in the deck, moving the bottom half to the top of the draw pile. If no value is passed to the method, Dealer will place the top card at the bottom of the deck.

// Top card is now placed at the bottom of the deck
dealer.cut();

// Top 13 cards are now placed at the bottom of the deck
dealer.cut(13); 

Draw

Returns the number of cards requested from the draw pile for use in the game. If no value is passed to the method, Dealer will draw one card.

// Returns the top card from the deck
dealer.draw();

// Returns the top 5 cards from the deck
dealer.draw(5); 

Discard

Moves the number of cards specified from the draw pile to the discard pile without revealing the value to the game. If no value is passed to the method, Dealer will discard only the top card in the pile.

// The first card in the draw pile is discarded
dealer.discard();

// The first 3 cards in the draw pile are discarded
dealer.discard(3); 

Reset Game

Resets the draw & discard piles to the default deck position.

dealer.reset();

Remaining Cards

Returns a count for the remaining cards in the draw pile.

dealer.remainingCards();
