logdown: Markdown Debug Utility

logdown is a versatile JavaScript debug utility designed for both browser and Node.js environments, providing a consistent logging interface with built-in Markdown formatting support. Currently stable at version 3.3.1, the library maintains a fairly active release cadence within its major version 3, introducing enhancements such as custom transports, optimized bundle sizes through Webpack, improved cross-environment compatibility, and modular internal architecture. Its key differentiators include automatic Markdown parsing for log messages, seamless delegation to native console methods, and compatibility with standard debugging mechanisms like Node.js's `NODE_DEBUG` environment variable and browser `localStorage.debug`. The library is lightweight, with the browser version having no external dependencies and a minimal gzipped footprint, making it suitable for performance-sensitive applications.
