title: Including a script src into js file
body: <p>Im trying to integrate a firebase config into my <code>js</code> file rather than directly into html file. Given:</p>
  
  <pre><code>&lt;script src="https://www.gstatic.com/firebasejs/3.4.0/firebase.js"&gt;&lt;/script&gt;
  &lt;script&gt;
    // Initialize Firebase
    var config = {
    .......
    }
  &lt;/script&gt;
  </code></pre>
  
  <p>and my js file:</p>
  
  <pre><code>$(function() {
  ......
  }
  </code></pre>
  
  <p>how can I integrate the line <code>&lt;script src="https://www.gstatic.com/firebasejs/3.4.0/firebase.js"&gt;&lt;/script&gt;</code> into my js file ?</p>
