Recently I installed node.js on my Windows 7 machine.

On execution of JavaScript, I get an undefined message along with successful execution of the expression.

What's wrong here? I have not noticed any other side effects.

The JavaScript functions always return something. If you don't specify something to return in the function, 'undefined' is returned by default (you can check this out in Firebug too).

Don't worry though, this doesn't affect anything, you can ignore it.
