Creates an array of unique values present in all provided arrays using strict equality for comparisons, i.e. ===.

haystack.filter([1, 2, 3], [5, 2, 1, 4]);
// => [1, 2]

haystack.filter('a', ['b', 'a']);
// => ['a']

haystack.filter(['a', 'b'], 'a');
// => ['a']

haystack.filter(['c', 'd'], ['d', 'e', 'c']);
// => ['c', 'd']

haystack.filter(['f', 'g'], 'f, h, i');
// => []

haystack.filter(['f', 'g'], 'f, h, i', ',');
// => ['f']

Optionally pass a string separator as a third parameter.

haystack.filter(['f', 'b'], 'a,f,k,l', ',');
// => ['f']

haystack.filter(['find', 'exclude'], 'A find and match utility', ' ');
