Joining file paths correctly is crucial for building Node.js applications that work across different operating systems. As the creator of CoreUI with over 11 years of Node.js development experience, I’ve learned that string concatenation for paths leads to platform-specific bugs. The path.join() method provides a safe, cross-platform solution for combining path segments with the correct separators.

Working with file paths in Node.js requires careful handling to ensure cross-platform compatibility between Windows, macOS, and Linux. As the creator of CoreUI with over 11 years of Node.js development experience, I use the path module extensively for building robust backend applications. The path module provides utilities for working with file and directory paths in a platform-independent way.
