But what about not so computation-heavy tasks like parsing HTTP requests, interacting with databases, generating and serving responses based on the input, templates, reasonably simple logic and the data? And if it's not fast then why even consider it when there are more well-established alternatives like Ruby for those who like the syntax, ASP.Net/Core, Python/Django, Node/Express, Scala/Play for the FP lovers etc? I've been previously told it's key features are it's super fast, functional and Ruby-like.
