Ensure consistently formatted POSIX paths across platforms. ensure-posix-path converts Windows-style paths (using backslashes) to forward-slash-delimited POSIX paths, making cross-platform development more predictable. Helpful for tools where consistent path formatting is crucial, regardless of the operating system. It accepts both relative and absolute paths, returning a clean, POSIX-compliant version. This simplifies path manipulation and avoids platform-specific issues in your Node.js projects.
