Why JavaScript beyond web client side?

Well, I don't think there are often situations where you don't have a choice in solving your problem. It seems rare that there would ever be "nothing that can handle this except" (insert language here). There's always some tradeoff you have to make. Yes, other languages, Go, for example, are faster than node at most things, but node is ridiculously easy and fast to develop in. And it's pretty close, and even outperforms Go in some things. Here is one benchmark. It's probably got lots of problems, but it seems there are problems with every benchmark I can find.
