Converting %d to NaN

[Proful]

I am trying to convert some Node.js side script to coffeescript.
console.log("Listening on port %d",3000);

converting to
console.log "Listening on port NaN", 3000

Is it expected behavior?

Not at all... thanks for the report.

By the way this only affects the Node version (tried with 0.4.7), running it in a browser (http://ricostacruz.com/js2coffee/) seems to work properly.

Looks like an inconsistency with JSON.stringify behavior. This is because in js2coffee/node, the output is being thrown to STDOUT using console.log(string).
