title: Substring and Join in Twig
body: <p>I know it's possible to join an array in twig, like so:</p>
  
  <pre><code>['name_first', 'name_second', 'name_third']|join(', ')
  {# name_first, name_second, name_third #}
  </code></pre>
  
  <p>I also know I can use <code>[5:]</code> to remove the 'name_' part of each element. But, is it possible combine both, without looping over the whole thing. So, the final result will be:</p>
  
  <pre><code>first, second, third
  </code></pre>
