lodash

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
