title: How does AMP-HTML page load javascript from rails/app/assets/javascript folder?
body: <p>Before AMP I was using <code>javascript_include_tag 'application'</code> for including all js files but now after AMP implementation it shows error:</p>
  
  <pre><code>The tag 'script' is disallowed except in specific forms
  </code></pre>
  
  <p>AMP supports <code>async</code> attribute and <code>application/json+ld</code> type in <code>script</code> tag</p>
