Little array puzzle. Explanation not clear
<p>Im doing this js set of tests: 
<a href="https://github.com/rmurphey/js-assessment" rel="nofollow">js-assessment</a></p>

<p>One of the test says:</p>

<pre><code>  it("you should be able to find all occurrences of an item in an array", function() {
      var result = answers.findAllOccurrences('abcdefabc'.split(''), 'a');

      expect(result.join(' ')).to.be('0 6');
    });
</code></pre>

<p>I don't get where the <code>'0 6'</code> result came from.
The task is to find occurrences of <code>a</code>, but in that array there are only two a's.</p>
