title: Reduce nested array to string?
body: <p>I have the following array:</p>
  
  <pre><code>arr = [["Example"]]
  </code></pre>
  
  <p>I need to reduce it to just <code>"Example"</code> (basically, just remove the array).</p>
  
  <p>I know I could do <code>arr[0][0]</code>, but am curious if there's a simple method to just remove the string from the array without using indexes.</p>
  
  <p>For clarification...there will only ever be a single item in the array.</p>
