remove_array_odds-no_looping4.js

/**
    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

var numbersArray =  [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 100, 112, 113];


//initial array
window.prompt('The original numbers array was : ', numbersArray);

//final array output (I think this is not a good practice talking about maintenance and readability of code, this is just a creative solution using regular expresions and string manipulation)
window.prompt( 'The evens numbers are 1: ', numbersArray.join().match(/\w?(\d+)*[24680]/g) );
