title: Coalesce a value in Meteor Jade
body: <p>In a template, I do this</p>
  
  <pre><code>if description
      p.editable= description
  else
      p.editable
          | No description. Click to edit.
  </code></pre>
  
  <p>I wonder if there's a way to coalesce a value like in JavaScript:</p>
  
  <pre><code>p.editable #{description || 'Click to edit'}
  </code></pre>
  
  <p>But this is incorrect syntax in Jade</p>
