The variable naming convention used here could be improved for clarity. I prefer appending `El` to variables that hold DOM elements, as it makes identifiers like `tableEl` clearer and helps avoid ambiguity between variables such as `table` and `row`. Also, the variable named `table` does _not_ actually represent a table element; it would be more accurate to name it `data` or `tableData` to better reflect its purpose.

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.
