lodash orderBy on nested property

Question

I'm using v4.11.0. I would like sort objects based on milliseconds property. Here's the array :

[
    {
        "name": "bug12755.xml",
        "list": "bugs42",
        "start-date": "2015-09-14",
        "age": {
            "text": "7 months",
            "milliseconds": 18381227304
        }
    },
    {
        "name": "bug12922.xml",
        "list": "bugs42",
        "start-date": "2015-08-27",
        "age": {
            "text": "8 months",
            "milliseconds": 19936427304
        }
    },
    {
        "name": "bug13183.xml",
        "list": "bugs50",
        "start-date": "2015-08-27",
        "age": {
            "text": "8 months",
            "milliseconds": 19936427305
        }
    }
]

I'm missing something fundamental about the iteratee function. I have this but does not seem to sort the array. Thanks in advance!

 _.orderBy(list, function(item) {
            return item.age.value;
        }, ['desc']);

It seems that you are ordering by the wrong property value.

_.orderBy(list, item => item.age.milliseconds, ['desc']);

Be careful anyone sorting with letters. Lodash doesn't do natural sort order on letters https://stackoverflow.com/questions/37848030/lodash-how-to-do-a-case-insensitive-sorting-on-a-collection-using-orderby – steampowered Jun 25 '17 at 00:45

A simple example on how you can use the Lodash: orderBy to sort based on inner attributes.

hotels = _.orderBy(hotels, 'account.id', 'desc');

this approach is much better as it's simpler and gets the job done with less complexity. – Newteq Developer Mar 18 '19 at 12:54

A simple example on how you can sort by another property if one is undefined:

import _ from "lodash";

const orderItems = (items) => _.orderBy(items, (item) => item.displayName || item.name, ["asc"]);
