iterable.rotate(x, [n]);
// x: an iterable
// n: rotate amount (+ve: left, -ve: right) (0)

const iterable = require("extra-iterable");

var x = [1, 2, 3, 4];
[...iterable.rotate(x, 1)];
// [ 2, 3, 4, 1 ]

[...iterable.rotate(x, 2)];
// [ 3, 4, 1, 2 ]

[...iterable.rotate(x, -1)];
// [ 4, 1, 2, 3 ]
