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']); 

Answer 1

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

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