sort array of numeric strings with Lodash

sortBy can be used with a function instead of a property name.

_.sortBy(arrData, function (obj) {
    return parseInt(obj.rhid, 10);
});

This can be achieved using arrow notation like:

_.sortBy(arrData, (obj) => parseInt(obj.val, 10));

If you want to do more than one field like @GunasekaranR asked, you can also do it with arrow notation:

_.sortBy(arrData, [
  (obj) => parseInt(obj.first_val, 10),
  (obj) => parseInt(obj.second_val, 10)
]);

The second way uses first_val as the main sorting object, with second_val being the tie breaker.
