lodash.sortby

What is lodash.sortby?

The lodash.sortby package is a part of the Lodash library which provides utility functions for common programming tasks using a functional programming paradigm. This package offers a convenient way to sort collections like arrays and lists based on one or more iteratees.

What are lodash.sortby's main functionalities?

Sorting an array of values

This feature allows you to sort an array of objects by a specific property. In the code sample, the 'users' array is sorted by the 'user' property.

const _ = require('lodash.sortby');
const users = [
  { 'user': 'fred',   'age': 48 },
  { 'user': 'barney', 'age': 36 },
  { 'user': 'fred',   'age': 40 },
  { 'user': 'barney', 'age': 34 }
];

const sortedUsers = _.sortBy(users, [function(o) { return o.user; }]);

Sorting by multiple criteria

This feature allows sorting by multiple criteria. In the code sample, the 'users' array is first sorted by the 'user' property and then by 'age'.

const _ = require('lodash.sortby');
const users = [
  { 'user': 'fred',   'age': 48 },
  { 'user': 'barney', 'age': 36 },
  { 'user': 'fred',   'age': 40 },
  { 'user': 'barney', 'age': 34 }
];

const sortedUsers = _.sortBy(users, ['user', 'age']);
