difference

Gives values of an array not present in another.

array.difference(x, is);
// x:  an array
// y:  another array
// fn: compare function (a, b)

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

var a = [1, 2, 3, 4, 5];
array.slice$(a, 2);
// [3, 4, 5]

a;
// [3, 4, 5]

var b = [1, 2, 3, 4, 5];
array.slice$(b, 2, 4);
// [3, 4]

b;
// [3, 4]
