Node.JS vs ASP.NET as backend server for my game

Node is not made for extensive computing. It’s just fast event loop, that why it shines in web dev. Net not so much better. Web, apis, messaging and such “light” and short lived thing are great made with them. C/++, Java, Go(?) are better suited for business computing. More low level, more control, less overhead. But for prototyping stuff, Node, and Net are shining. Just imho.
