Sort Unwind
Sorts an array by an array of ranks and retains the stochastic tenet of the initial array so you can undo back to the original shuffled state.
Install
npm install --save sort-unwind
Usage
import { unwind } from 'sort-unwind'
const suits = ['♥', '♠', '♣', '♦']
const ranks = [2, 0, 3, 1]
const [sortedSuits, tenet] = unwind(ranks, suits)
// sortedSuits <- ['♠', '♦', '♥', '♣']
// tenet <- [1, 3, 0, 2]
You can then restore the entropy back into the array, or perhaps apply that entropy to another array. Sort of like sending that array backward in time to the more chaotic state.
const names = ['spades', 'diamonds', 'hearts', 'clubs']
const [tenetNames, tenetRanks] = unwind(tenet, names)
// tenetNames <- ['hearts', 'spades', 'clubs', 'diamonds']
// tenetRanks <- [2, 0, 3, 1]
