I would argue that Async in F# is just a library. Async tasks are essentially just functions that are composed using the more general "workflow" syntax. The final composite Async must be explicitly run with a choice of scheduler. I suspect Libraries-not-frameworks is only advice for those using sufficiently expressive languages. So probably not appropriate advice for JavaScript.
