Node.js console.log not working -

simplest possible code in hello.js

(function() {     console.log("hello world!"); });

running : $node hello.js

there no output. if remove enclosing function, works properly. want use closure. ideas?

node version 0.10.30. ubuntu 12.04 x64

you,re not running function.

you should add function call:

(function() {   console.log("hello world!"); }).call();

or simply

(function() {   console.log("hello world!"); })();
