In this tutorial, we are going to discuss the sort records operation.

Sorting records is a critical operation when working with data in any programming language. In this tutorial, we'll explore how to effectively sort records in Node.js using the Array.prototype.sort() method. We'll cover sorting records in ascending and descending order, as well as custom sorting based on various criteria.

Prerequisites

Before we dive into the tutorial, ensure that you have Node.js installed on your computer. You can download and install it from the official Node.js website.

1. Setting Up the Project

Create a new folder for your project.

Open your terminal and navigate to the project folder using the cd command.

---

2. Creating Sample Data

To demonstrate sorting, let's start by creating a sample dataset. In a new JavaScript file named data.js, define an array of objects, where each object represents a record. Each record should have attributes that you want to use for sorting, such as an id, name, and score.

3. Sorting Records

Create a new JavaScript file named sort.js to write the sorting logic. Begin by importing the records array from the data.js file.

---

4. Running the Code

In your terminal, run the sort.js script using the Node.js command:

Observe the sorted records printed in the terminal. You'll notice that we've used the Array.prototype.slice() method to create a shallow copy of the array before sorting, ensuring that the original array remains unchanged.

5. Custom Sorting Criteria

You can implement custom sorting by modifying the sorting function. For instance, if you want to sort records alphabetically by name, you can use the following code:

Feel free to experiment with other sorting criteria based on your dataset's attributes.

6. Working with Date Records

Sorting by dates is also common. Suppose your records have a date attribute. You can sort them as follows:

In this tutorial, you've learned how to sort records in Node.js using the Array.prototype.sort() method. This versatile tool allows you to arrange data based on various criteria, making your applications more organized and user-friendly. By applying these concepts, you'll be well-equipped to manage and present data effectively within your Node.js projects.
