Gives values present in any iterable.
iterable.union(x, y, [fn]);
// x: an iterable
// y: another iterable
// fn: compare function (a, b)
const iterable = require('extra-iterable');
var x = [1, 2, 3, 4];
var y = [2, 3, 5];
[...iterable.union(x, y)];
// [1, 2, 3, 4, 5]
var y = [-2, -3, -5];
[...iterable.union(x, y, (a, b) => Math.abs(a) - Math.abs(b))];
// [1, 2, 3, 4, -5]
