title: Injecting Carbon in Handlebars Template
body: <p>I have a Handlebars template which renders articles on my site by fetching data through an API. The API is returning a timestamp that I'd like to convert into a human readable format. I could format the timestamp through JS but I was wondering whether I could inject Carbon, <code>diffForHumans()</code> to be specific, to do that on the fly. </p>
  
  <pre><code>&lt;script id="article-template" type="text/x-handlebars-template"&gt;
      &lt;div class="post-item"&gt;
          &lt;div class="post-item__thumb"&gt;
              &lt;img class="post-item__thumb__img" src="@{{ thumbnail_image }}"
                   alt="@{{ title }}"/&gt;
          &lt;/div&gt;
          &lt;div class="post-item__content"&gt;
              &lt;a class="post-item__title" href="@{{ url }}"&gt;@{{ title }}&lt;/a&gt;
              &lt;p class="post-item__meta"&gt;
                  by &lt;a href="#"&gt;@{{ author }}&lt;/a&gt; on @{{ published_at }}
              &lt;/p&gt;
              &lt;p class="post-item__teaser"&gt;@{{ excerpt }}&lt;/p&gt;
              &lt;a class="post-item__read-full" href="@{{ url }}"&gt;Read full article&lt;/a&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/script&gt;
  </code></pre>
  
  <p>Would it be possible to go about doing something like this?</p>
  
  <pre><code>    &lt;p class="post-item__meta"&gt; by &lt;a href="#"&gt;@{{ author }}&lt;/a&gt;
           on @{{ published_at }}{{ diffForHumans() }}
      &lt;/p&gt;
  </code></pre>
