var obj = {
  blake: 20,
  andrew: 10,
  matt: 45
};

var annotated = _.map(obj, function (value, key) {
  return {key: key, value: value};
});

var names = _.pluck(_.sortBy(annotated, 'value'), 'key');

@kaw2k - Niiiice. That's exactly the combo I'd figured I'd missed. I might argue that the sortBy piece is easier to reason about when you're sorting by a keyname - like value. But yours is definitely more compact.

And that curried version is tasty.

(Also, I think you meant _.values().)
