title: How to inject a value inside a string in pug
body: <p>Hello guys I am trying to inject a value inside a pug html attribute. I can not seem to find any documentation on how to do this. Here's my code</p>
  
  <pre><code>input(type='hidden', name='country', value='#{val.snippet.id.videoId}')
  </code></pre>
  
  <p>as you can imagine <code>val.snippet.id.videoId</code> is just a javascript variable I am passing from my server side. So I want to set the value attribute to that variable. Would really appreciate if someone points me to the right direction.</p>
