janus-shuffle v1.0.2
janus-shuffle
Janus-Shuffle applies davidbau's seedrandom
to power the randomness requirement of coolaj86's knuth-shuffle
, allowing a user to shuffle strings based on string-based seeds. Before shuffling, character occurernces are evenly applied to the string to guard against weight analysis. This library will work in NodeJS and on the browser.
Installation
npm install janus-shuffle
