Returning an odd or even number from array

Question

Just need help in identifying what I am doing wrong on this codewar challenge.

I realize this may be easy for some but please note I am just a beginner with Javascript.

Answer 1

Another possible way:

function myFunction(integers) {
  var odds = integers.filter(function(num) {return num % 2});
  var evens = integers.filter(function(num) {return !(num % 2)});
  return evens.length == 1 ? evens[0] : odds[0];
}
