zip

Combines values from iterables. 🏃 📼 📦 🌔 📒

iterable.zip(xs, [fm], [ft], [vd]);
// xs: iterables
// fm: map function (vs, i, xs)
// ft: till function (dones)
// vd: default value

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

var x = [1, 2, 3];
var y = [4, 5, 6];
[...iterable.zip([x, y])];
// [ [ 1, 4 ], [ 2, 5 ], [ 3, 6 ] ]

[...iterable.zip([x, y], 0, ([a, b]) => a + b)];
// [ 5, 7, 9 ]
