isDisjoint

Checks if iterables have no value in common. 🏃 📼 📦 🌔 📒

iterable.isDisjoint(x, y, [fc], [fm]);
// x:  an iterable
// y:  another iterable
// fc: compare function (a, b)
// fm: map function (v, i, x)

⏱️ Compare function => O(n²).

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

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

iterable.isDisjoint(x, [-2, -5]);
// true

iterable.isDisjoint(x, [-2, -5], (a, b) => Math.abs(a) - Math.abs(b));
// false

iterable.isDisjoint(x, [-2, -5], null, v => Math.abs(v));
// false
