This is all I personally ever need.

  function $(q) { return document.querySelector(q) }

I prefer:-

  function $(q, parent) { return (parent || document).querySelector(q); }

I'd also wrap it in a `[].slice.call`:

    function $(q, parent) {
        parent = parent || document;
        return [].slice.call(parent.querySelectorAll(q));
    }

Also see ES2015's Array.from()

    Array.from(<NodeList or other iterable>)

If we're golfing,

    $ = document.querySelector.bind(document);

would be sufficient? ;)

(var | let | const) $ = ::document.querySelector;

Huh, my joke actually turned into me learning something, thanks!

Hehe, You're welcome – I do take golfing very serious ;)
