@ludicity it's just a bonus that it's an order of magnitude faster, has a standard library that's so good you barely need anything else (and what you do bring in from third party libs is mostly made by grownups who write clear, concise, no bullshit, code), and has a memory footprint that's dramatically smaller.
It's such a low bullshit language, I can't imagine using anything else for web services and web app backends.
