go & dart, they are bold attempts if you are from a java background, however now that most of us code in Ruby, Python, PHP etc, they don't appear quite state of the art. The syntax does not appeal unfortunately.
Please don't lump Go in with Dart. It is a totally different beast and a pretty nice language over all. Considering the people who are writing the Go language (eg. Pike, Cox, etc...) and the language itself it really doesn't have anything to do with Java.
tl;dr Dart looks stupid and isn't what I am looking for. Go is a pretty good language for the right use case.
maybe someone will develop a certain node.dart?
