Feature #16039
Updated by cha1tanya (Prathamesh Sonpatki) over 5 years ago
I woud like to propose `Array#contains?` which will check if the one array is part of another array. Implementation can be as follows: ``` def contains?(other) (other other - self).empty? end ``` Some test cases: ``` [1, 2, 3].contains?([2, 3]) => true [1, 2, 3].contains?([]) => true [1, 2, 3].contains?([1, 2, 3, 4]) => false [].contains?([]) => true [].contains?([1, 2, 3, 4]) => false ```
