How does lodash.sortBy work?
lodash.sortBy is a method that sorts an array of objects based on a specified key or keys in ascending or descending order. The method takes two arguments: the array to sort and the key or keys to sort by. The key or keys can be a string representing a property of the objects in the array to sort by, or they can be a function that returns the value to sort by. By default, lodash.sortBy sorts the array in ascending order. To sort in descending order, you can specify the key or keys as an array and prepend a - sign to the keys that should be sorted in descending order. For example, the following code sorts an array of objects representing people by their age in ascending order: javascript Copy code {{{{{{{ const _ = require('lodash'); const people = [ { name: 'Alice', age: 25 }, { name: 'Bob', age: 30 }, { name: 'Charlie', age: 20 }, ]; const sortedPeople = _.sortBy(people, 'age'); console.log(sortedPeople); In this code, we use lodash.sortBy to sort the people array by the age property of each object. The resulting sorted array is stored in the sortedPeople variable, and is then logged to the console using console.log(). The output of this code will be: yaml Copy code {{{{{{{ class="!whitespace-pre hljs language-yaml">[ { name: 'Charlie', age: 20 }, { name: 'Alice', age: 25 }, { name: 'Bob', age: 30 } ] Overall, lodash.sortBy provides a simple and convenient way to sort an array of objects based on a specified key or keys in ascending or descending order, making it easier to work with complex data structures in JavaScript.

const _ = require("lodash"); const users = [ { name: "Alice", age: 25 }, { name: "Bob", age: 30 }, { name: "Charlie", age: 20 }, ]; const sortedUsers = _.sortBy(users, "age"); console.log(sortedUsers);
In this example, we have an array of users objects, each of which has a name and age property. We use lodash.sortBy to sort the users array based on the age property of each object. The resulting sorted array is stored in the sortedUsers variable, and is then logged to the console using console.log(). The output of this code will be: yaml Copy code
