rotate

Rotates values in iterable.

array.rotate(x, n);
// x: an array
// n: rotate amount (-ve: left, +ve: right)

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

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

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

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