/**
    Code Challenge Needed:
        Using Javascript, given an array of n integers (example: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 100, 112, 113] ), remove all odd numbers, leaving only the even numbers.

    Rules:
        NO LOOPING. This means native methods, or libraries that loop for you are not allowed either.

    Supply the answer on github via Gist
