Places values of an iterable between another. 🏃 [:vhs:] 📦 🌔 📒

iterable.intermix(x, y, [s], [t], [m], [n]);
// x: an iterable
// y: another iterable
// s: step size for x (1)
// t: step size for y (1)
// m: number of values from x (s)
// n: number of values from y (t)

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

var x = [1, 2, 3, 4];
var y = [10, 20, 30];
[...iterable.intermix(x, [10])];
// [ 1, 10, 2, 10, 3, 10, 4 ]

[...iterable.intermix(x, y)];
// [ 1, 10, 2, 20, 3, 30, 4 ]

[...iterable.intermix(x, y, 2)];
// [ 1, 2, 10, 3, 4 ]

[...iterable.intermix(x, y, 1, 2)];
// [ 1, 10, 20, 2, 30, 10, 3, 20, 30, 4 ]
