Fisher-Yates Shuffle

A JavaScript implementation of the Fisher-Yates Shuffle algorithm.

Requirements

• NodeJS 6+

Installation

npm install fisher-yates-shuffle --save

Usage

const shuffle = require('fisher-yates-shuffle');
const deck = ['a', 'b', 'c', 'd'];
const shuffledDeck = shuffle(deck);

const randomizer = function() {
    return 0.321
};
const shuffle = require('fisher-yates-shuffe');
const deck = ['a', 'b', 'c', 'd'];
const shuffledDeck = shuffle(deck, randomizer);

Notes

• It clones the given Array, so if it's rather large, make sure you have enough memory allocated.
• This library is still rather naïve and could be improved. If you have any suggestions, please open up an Issue or a Pull Request.
