Combines values from iterables. 🏃 📼 📦 🌔 📒
Similar: [cartesianProduct], [zip].
iterable.zip(xs, [fm], [ft], [vd]);
// xs: iterables
// fm: map function (vs, i, xs)
// ft: till function (dones)
// vd: default valueconst iterable = require('extra-iterable');
var x = [1, 2, 3];
var y = [4, 5];
[...iterable.zip([x, y])];
// [ [ 1, 4 ], [ 2, 5 ] ] (shortest)
[...iterable.zip([x, y], ([a, b]) => a + b)];
// [ 5, 7 ]
[...iterable.zip([x, y]), null, iterable.some];
// [ [ 1, 4 ], [ 2, 5 ] ] (shortest)
[...iterable.zip([x, y], null, iterable.every, 0)];
// [ [ 1, 4 ], [ 2, 5 ], [ 3, 0 ] ] (longest)
[...iterable.zip([x, y], null, iterable.head, 0)];
// [ [ 1, 4 ], [ 2, 5 ], [ 3, 0 ] ] (first)
