title: How to console.log in pug?
body: <p>How can I console.log the data coming from the backend in pug?</p>
  
  <p>For instance, this is my backend in expressjs:</p>
  
  <pre><code>    res.render("streams/show", {
          stream: cleanStream
      });
  </code></pre>
  
  <p>in show.pug, I want to inspect the data from steam:</p>
  
  <pre><code>- var species = stream.species;
  - var fields = [];
  - for (var key in species) fields.push(key)
  - console.log(fields)
  </code></pre>
  
  <p>I can't see anything on my Developer Tool on my Chrome.</p>
  
  <p>Any ideas?</p>
