[D] Golang better option for Back-end Web Development instead of Javascript?

As title says, what do you think??. I personally think Go would be Javascript overall killer in almost all the cases of back-end web development. For saying some:
1. Performance and Efficiency -> Go is a statically typed and compiled language
2. Concurrency Model -> handling multiple, simultaneous tasks, instead of JS event-driven and callback-based model.
3. Scalability
Thanks for reading.
