How can I use lodash/underscore to sort by multiple nested fields?

Question

I want to do something like this:

var data = [
    {
        sortData: {a: \'a\', b: 2}
    },
    {
        sortData: {a: \'a\', b: 1}
    },
    {
        sort

Update: See the comments below, this is not a good solution in most cases.

Someone kindly answered in the issue I created. Here's his answer, inlined:

_.sortBy(data, function(item) {
   return [item.sortData.a, item.sortData.b];
});

I didn't realize that you're allowed to return an array from that function. The documentation doesn't mention that.
