Merge values from sorted iterables.

Similar: [sort], merge.


function merge(xs, fc, fm)
// xs: iterables
// fc: compare function (a, b)
// fm: map function (v, i, x)
const xiterable = require('extra-iterable');

var x = [1, 3, 5, 7];
var y = [2, 4, 8];
[...xiterable.merge([x, y])];
// → [
//   1, 2, 3, 4,
//   5, 7, 8
//]

var y = [-2, -4, -8];
[...xiterable.merge([x, y], (a, b) => Math.abs(a) - Math.abs(b))];
// → [
//   1, -2,  3, -4,
//   5,  7, -8
//]

[...xiterable.merge([x, y], null, v => Math.abs(v))];
// → [
//   1, -2,  3, -4,
//   5,  7, -8
//]
