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>) https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/from https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...

  If we're golfing, $ = document.querySelector.bind(document); would be sufficient? ;)

    (var | let | const) $ = ::document.querySelector; with experimental ES7 syntax :D https://github.com/zenparsing/es-function-bind https://github.com/zenparsing/es-function-bind
