From what I've experienced code based frameworks are often used because the language itself doesn't handle that case well on its own. In the case of F#, JS, etc, using DI again as an example, partial completion/currying once you get your head around it means that quite often programs are just chained one line factories (similar to the one line you used to register your singleton/instance in a DI framework so no more code bloat). As a bonus you learn something that is multi applicable, not just for DI and doesn't bring in any more "magic" or runtime errors if a registration is missing because the compiler catches it. Everything is just functions/modules which means mocking is a breeze too, refactoring is easier, etc.

This is my own personal experience here mentoring dev's in both technologies, especially when they come from different backgrounds. YMMV.
