title: jQuery :first deprecated - rewrite?
body: <p>How would I re-write something like this in jQuery 3.4.1 or vanilla JS:</p>
  
  <pre><code>$("#ResultsTable tr:not(:first)").remove();
  </code></pre>
  
  <p>with :first being deprecated?
  (<a href="https://api.jquery.com/first-selector/" rel="nofollow noreferrer">https://api.jquery.com/first-selector/</a>) </p>
  
  <p>I need to remove all the rows other than the first one.</p>
