title: Filtering out a class members with JavaScript
body: <p>It's probably a simple problem, but I've only just started coding, plz bear with me...</p>
  <p>I have a bunch of elements, with all the same two classes, partWiel and partWielIn. I want to remove the second class from all of them, except the first.</p>
  <p>Basically, this is what I want, but I think I can't use mathematical operators inside those square brackets:
  <code>partWiel[&gt;0].classList.remove(&quot;partWielIn&quot;);</code></p>
  <p>How can I do this?</p>
