filedirname simplifies working with __filename and __dirname across different module types (ESM and CJS) in Node.js. It provides a consistent way to retrieve the current file's and directory's paths, eliminating boilerplate code required to handle discrepancies between module systems. This utility enhances code portability and reduces potential errors when migrating projects across environments or adopting modern JavaScript features. It's a lightweight and straightforward solution for developers seeking a unified approach to file and directory path resolution.
