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

The awesome, simple way is:

_.sortBy(data, [function(item) {
    return item.sortData.a;
}, function(item) {
    return item.sortData.b;
}]);

I found it from check the source code of lodash, it always check the function one by one.

Hope that help.
