I'd say for the web, the language is not as important as the ecosystem, in particular, as the frameworks and libraries for web development available.

In that regard, for a single developer or a small team your best options are Rails,Laravel or Django.

I prefer Rails because of its strong opinions, specially on frontend.

Once your idea makes you millionaire, you can start thinking about the purity and the universal beauty of Go, Clojure, Typescript, React, RxJS, lambdas, etc.
