Are you seeing any decorator or OOP style in React? Yet plenty of dependencies are automatically injected without the OOP jargon, if you want to see a pure JS example of auto DI go check angular 1.5 dep system, and Vuejs. |

I totally agree there are other good/better options (as evidenced by react and many others), but I don't think this is an entirely fair comparison. The main "DI" alternatives in React are hooks, context, and imports, none of which could really replace traditional IoC containers on the backend without some modifications.
I think the main thing that makes automatic DI easy with OOP is the clear separation between dependencies (constructor parameters), and method parameters. Admittedly, this is totally possible with FP, but requires some good conventions and doesn't seem to be nearly as popular.
I also think most OOP langs have terrible syntax for constructors, which makes it look clunkier than it really is. Primary constructors (e.g. kotlin) make this not much more verbose than the FP alternative.

Yes it's vanilla JS, but I doubt there's many FP people that would call that functional. The examples I saw are all just using JS functions as "discount classes", which definitely aren't pure or functional.
