Including a script src into js file
<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>
