title: How to Remove Unused javascript From Website
body: <p>I'm trying to speed up my website. I used <a href="https://www.unused-css.com/" rel="noreferrer">www.unused-css.com/</a> to trim away excess CSS, but I cannot find anything similar for JavaScript. Is there an online service that can detect the <em>js code</em> being used and then trim away the unused code?</p>
  
  <p>Here is the website with the problem: <a href="http://iqtests4kids.com" rel="noreferrer">IQ Tests for Kids</a>
  I'm using bootstrap code and it is very bloated. I'm sure that I'm only using a fraction of js because I trimmed down my HTML as well.</p>
