``` go // +build js package main import "github.com/gopherjs/gopherjs/js" func log(i ...interface{}) { js.Global.Get("console").Call("log", i...) } func main() { print("print message") log(" log message") } ``` ``` gopherjs run main.go ``` I get no output on Windows 7, 64 bit / Node 4.2.1 + sourcemap lib. This is a pity, since it is very useful for quick and dirty prototyping. It used to work without problems.
