title: Load JS script after another one is loaded
body: <p>here's my code:</p>
  
  <pre><code>&lt;script src='app.js' defer&gt;&lt;/script&gt; //very big js file
  //lots of html stuff
  &lt;script&gt; alert(1);&lt;/script&gt;
  </code></pre>
  
  <p>The problem is, that those are loaded asynchronously. Is there a way to wait for the second script until the first one is loaded?</p>
