Merges values from iterables. 🏃 📼 📦 🌔 📒

Similar: interleave, intersperse.

iterable.interleave(xs);
// xs: iterables

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

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

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

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

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