code: function hash() {
  	var i = 0,
  		args = arguments,
  		length = args.length,
  		obj = {};
  	for (; i < length; i++) {
  		obj[args[i++]] = args[i];
  	}
  	return obj;
  }
docs: Take an array and turn into a hash with even number arguments as keys and odd numbers as
  values. Allows creating constants for commonly used style properties, attributes etc.
  Avoid it in performance critical situations like looping
