I want to do something like this:

var data = [

    {

        sortData: {a: 'a', b: 2}

    },

    {

        sortData: {a: 'a', b: 1}

    },

    {

        sortData: {a: 'b', b: 5}

    },

    {

        sortData: {a: 'a', b: 3}

    }

];



data = _.sortBy(data, [sortData.a, sortData.b]);



_.map(data, function(element) {console.log(element.sortData.a +   + element.sortData.b);});

And have it output this:

a 1

a 2

a 3

b 5

Unfortunately, this doesn't work and the array remains sorted in its original form. This would work if the fields weren't nested inside the sortData. How can I use lodash/underscore to sort an array of objects by more than one nested field?

I've turned this into a lodash feature request: https://github.com/lodash/lodash/issues/581
