iterable.intersectionOn(x, y, [fn], [ths]);
// x:   an iterable
// y:   another iterable
// fn:  map function (v, i, x)
// ths: this argument

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

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

[...iterable.intersectionOn(x, [-2, -3, -5], v => Math.abs(v))];
// [ 2, 3 ]
