title: Equivalent to $.load without jQuery
body: <p>I want to load some Jade content into a certain div on button click. I have found how to do this with jquery, there are several posts on it, and essentially what I want to do is </p>
  
  <pre><code>$('#div').load('/somePage');
  </code></pre>
  
  <p>However, I am unable to use jQuery in my project. Is there an equivalent function in vanilla javascript?</p>
