title: How to add content to html body using JS?
body: <p>I have many <code>&lt;section&gt;</code> in my html <code>&lt;body&gt;</code> and want to add more through javascript. However, using <code>innerHTML</code> is just replacing my existing sections with new ones, instead of adding them to the old ones.</p>
  
  <p>What else can I use?</p>
