Rearranges values in arbitrary order.

This is part of package extra-array.

array.shuffle$(x, [n]);
// x: an array (updated)
// n: random seed 0->1
// --> x

const array = require('extra-array');

var x = [1, 2, 3, 4, 5];
array.shuffle(x);
// [ 1, 5, 4, 3, 2 ]

x;
// [ 1, 5, 4, 3, 2 ]

var x = [1, 2, 3, 4, 5];
array.shuffle(x, 0.3);
// [ 4, 5, 2, 3, 1 ]

var x = [1, 2, 3, 4, 5];
array.shuffle(x, 0.3);
// [ 4, 5, 2, 3, 1 ]
