Gives values that cycle through an iterable. 🏃 [:vhs:] 📦 🌔 📒

iterable.cycle(x, [i], [n]);
// x: an iterable
// i: start index (0)
// n: number of values (-1 => Inf)

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

var x = [1, 2, 3];
[...iterable.cycle(x, 0, 2)];
// [ 1, 2 ]

[...iterable.cycle(x, 0, 4)];
// [ 1, 2, 3, 1 ]

[...iterable.cycle(x, 1, 6)];
// [ 2, 3, 1, 2, 3, 1 ]
