Missing shuffle function for arrays in javascript. This is Fisher–Yates shuffle, and it's very fast.
npm install mess
var mess = require("mess");
console.log(mess([1,2,3,4,5,6,7,8,9,0]));
// output will be something like:
// [ 7, 9, 2, 0, 6, 8, 5, 3, 1, 4 ]
Because naming modules is hard and shuffle is already taken.
