I'm intrigued why would you pick Go, out of all languages out there - or conversely, why would you pick React and Redux as the UI model to emulate when using Go. Go is an unapologetically structural language, which eschews both most OOP and Functional Programming patterns. The Redux model, on the other hand, is strongly rooted in functional programming, and demands immutable data structures, something that is quite hard to do with Go. You would have to deep-clone every map and slice, which is extremely cumbersome and error prone in Go. Or perhaps you could just create a mutable store (this is what the TodoMVC does), but then you lose all the advantages of Redux like predictability, reproduceability and the time-travelling debugger.
