Introduction

In this guide, we'll dissect a common problem involving the bulkWrite method and provide clear solutions to ensure your code works as intended.

Problem Overview

Consider the following scenario: You have a collection of users and you want to perform bulk updates on a set of documents in your MongoDB database. However, upon execution, you notice that no documents are actually updated. This situation is often caused by asynchronous behavior in JavaScript, particularly when using methods like forEach(), which do not handle awaiting properly.
