Async parallel is a powerful utility library for Node.js that allows you to execute multiple asynchronous tasks simultaneously, providing a significant performance boost to your applications. It enables you to manage the execution of these tasks in parallel and gather their results once they all complete. This is particularly useful when dealing with I/O operations, such as making multiple API calls or performing database queries. Installation: Before diving into the code examples, we need to install the async library using npm. Open your terminal and run the following command: npm install async
