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         


        

Answer 1

With ES6 easy syntax and lodash

sortBy(item.sortData, (item) => (-item.a), (item) => (-item.b))
