title: Eslint rule for no empty lines within method?
body: <p>The repo I'm working in has no empty lines within a method</p>
  <p>For Example</p>
  <p><div class="snippet" data-lang="js" data-hide="true" data-console="true" data-babel="false">

  <p>When I google search I see rules for <code>no-multiple-empty-lines</code>, <code>padding-line-between-statements</code>, but no rule that dissalows empty lines within the method.</p>
  <p>Is there a way to force a live syntax check for this? I'm using VSCode, and I would just like some kind of red warning or underline whenever a method contains an empty line</p>
