What? It's anything but the syntax. The automatical live updates and the latency, the diff algorithm and the size of the payload, no client/api/controllers/routes needed, the scalability and stability, and the free clustering behind the framework. Can you rebuild this demo in Go or Scala in 15 mins or in 1 hour, correctly push any updates to the client while maintaining the robustness and sharding across the cluster? Writing stateful services correctly is very hard using an average web framework. I need at least 1 day to implement the same in Go or Scala, only the functionality but neither the clustering nor the optimization. And I'm considering I myself a functional programmer that is very familiar with Scala.
