Lodash _.sortByOrder numeric string

Question

I sort collection of objects with single primary key:

mydata = _.sortBy(mydata, function (obj) {
    return parseInt(obj[pk], 10);
});

But I cannot sort this numeric strings when is a composite key like ["RHID","CD_DOC_ID","SEQ"]

Please provide a sample of mydata, and the expected output. — Adam Boduch

In Lodash v3 do:

mydata = _.sortByAll(
  mydata, 
  [
    function (obj) {
      return parseInt(obj["RHID"], 10);
    },
    function (obj) {
      return parseInt(obj["CD_DOC_IC"], 10);
    },
    function (obj) {
      return parseInt(obj["SEQ"], 10);
    }
  ]
);

In Lodash v4: replace _.sortByAll with _.sortBy

If you also want to specify the sorting direction, use _.sortByOrder (v3) or _.orderBy (v4) instead.
