Gambler

Gambler is a simple module for shuffling a "deck of cards" and choosing a random card within that deck, where a "deck" is an array of objects. The deck can be an array of any type objects, Gambler doesn't care. Gambler does not modify the deck given to it. Instead, it makes a deep copy and operates on that deck.

Gambler uses the Knuth Shuffle when shuffling cards. When picking a card, it uses the SJCL prng class to pick the card.

Install

npm install --save gambler

Example

var gamblerFactory = require('gambler');
var deck = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
var gambler = gamblerFactory(deck);
 
gambler.shuffleDeck();
 
console.log('shuffled deck => ', gambler.deck);
console.log('drawn card => ', gambler.drawCard());
console.log('drawn card index => ', gambler.cardIndex);
// shuffled deck =>  [ 10, 5, 7, 6, 3, 2, 1, 4, 8, 9 ]
// drawn card =>  9
// drawn card index =>  9
 
// And then reusing the same gambler
deck = ['foo', 'bar', 'baz', 'foobar'];
gambler.deck = deck;
gambler.shuffleDeck();
console.log('shuffled deck => ', gambler.deck);
console.log('drawn card => ', gambler.drawCard());
console.log('drawn card index => ', gambler.cardIndex);
//shuffled deck =>  [ 'foobar', 'baz', 'foo', 'bar' ]
//drawn card =>  baz
//drawn card index =>  1
