====== JavaScript - Arrays - Array Diff ======

<code javascript>
var difference = function(compare){
  return Array.from(arguments).reduce(function(previous, current){
    return previous.filter(function(element){
      return current.indexOf(element) == -1;
    });
  });
};
</code>

diff([1,2,3], [1,2,3,4,5]) // => [4,5]
