Converting JSON to an array in jQuery is a common task that web developers encounter when handling data from APIs or other sources. JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for both humans and machines to read and write. Often, you need to parse JSON data and convert it into a JavaScript array for further manipulation. This guide will guide you through the process of converting JSON to an array using jQuery.

Step-by-Step Guide

Step 1: Include jQuery in Your Project
Before you start, make sure jQuery is included in your project. You can include it via a CDN (Content Delivery Network) or download it and host it locally.
