javascript - underscore filter array of nested objects -


i have following array of objects:

[{key: "test", values: [{key: "2015-05", values: [{1:2}, {3:4}]}, {}], ...]

i want filter key value left values after date.

i have this, resulting structure wrong

_.map(temp1, function(value, key) { return _.filter(value.values, function(v) { return v.key > "2015-05"; }); });

slight improvement on frank's answer:

var data = [    {      key: "1",       values: [        {key: "2014-05", values: [{1:2}, {3:4}]},        {key: "2015-05", values: [{1:2}, {3:4}]},        {key: "2013-05", values: [{1:2}, {3:4}]}      ]    },    {      key: "2",       values: [        {key: "2014-05", values: [{1:2}, {3:4}]},        {key: "2015-05", values: [{1:2}, {3:4}]},        {key: "2013-05", values: [{1:2}, {3:4}]}      ]    }  ];    var = _.map(data, (d) => {    d.values = _.filter(d.values, (v) => v.key > "2014");    return d;  });  console.log(a);
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>

no need parse date format, string comparison suffice. important note, despite _.map operation, modify original.
