The Challenge

[[See Video to Reveal this Text or Code Snippet]]

This approach has significant downsides:

Hardcoding the user path prevents portability.

Users on different systems will face "file not found" errors due to different user profiles.

So, how can you achieve a more dynamic solution? Let's dive into the solution!

The Solution: Using the path Module

Step-by-Step Guide

Require the Path Module: First, you need to import the path module.

Breaking Down the Code

require('path'): This imports the path module so we can use its methods.

Benefits of Using This Approach

Portability: By relying on environment variables, your path becomes user-agnostic, thereby enhancing the portability of your code.

Flexibility: This method works across different environments and user profiles, preventing runtime errors related to hardcoded paths.

Readability: The code remains clean and easy to understand, improving maintainability in the long run.
