Lodash.js (superset of Underscore.js)
It's good not to add a framework for every simple piece of logic, but relying on well tested utility frameworks can speed up development and reduce the amount of bugs.
Lodash produces very clean code and promotes a more functional programming style. In one glimpse it becomes clear what the intent of the code is.
OP's issue can simply be solved as:
const sortedObjs = _.sortBy(objs, 'last_nom');
More info? E.g. we have following nested object:
const users = [
{ 'user': {'name':'fred', 'age': 48}},
{ 'user': {'name':'barney', 'age': 36 }},
{ 'user': {'name':'wilma'}},
{ 'user': {'name':'betty', 'age': 32}}
];
We now can use the _.property shorthand user.age to specify the path to the property that should be matched. We will sort the user objects by the nested age property. Yes, it allows for nested property matching!
const sortedObjs = _.sortBy(users, ['user.age']);
Want it reversed? No problem. Use _.reverse.
const sortedObjs = _.reverse(_.sortBy(users, ['user.age']));
Want to combine both using chain?
const { chain } = require('lodash');
const sortedObjs = chain(users).sortBy('user.age').reverse().value();
Or when do you prefer flow over chain
const { flow, reverse, sortBy } = require('lodash/fp');
const sortedObjs = flow([sortBy('user.age'), reverse])(users);
