Probably because I first learned programming with JavaScript and very early started using jQuery, but I've always used prefixed `$` to indicate "This is a DOM element" (started doing this once jQuery stopped being so popular). So the example would be something like this for me:

  let table = [
    ['one','two','three'],
    ['four','five','six']
  ];
  let $body = document.body;
  let $table = document.createElement('table');
  $body.appendChild($table);

Always felt it worked out short and sweet, and as long as you're not refactoring a jQuery codebase, seems to work out well in practice.
