isDisjoint

Checks if arrays have no value in common.

Alternatives: compare, map.

array.isDisjoint(x, y, [fn]);
// x:  an array
// y:  another array
// fn: compare function (a, b)
// --> true if disjoint

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

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

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

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