Hello,
I had heard that there was server-side JavaScript, but knew nothing
about it until today when I found the websites:
http://www.hongkiat.com/blog/node-js-server-side-javascript/ and
http://nodejs.org/
I downloaded v0.6.18 onto my Windows Vista computer from the second
link and got the console prompt to work.
On type something like:
var a = 5;
var b = 6;
a + b;
I get the message "undefined" after the first two lines, but it still
works and gives the result as 11.
If I replace the last line by console.log(a+b);
I also get 11, but this is again followed by "undefined". Why am I
getting these messages?
Of rather more significance, if I create a file called helloworld.js,
and put in the file the line console.log("Hello World"); then type
"node helloworld.js", the prompt displays "..." then hangs, as if it
is waiting for something more, and cannot find the file. On typing
process.cwd() I am sure I am in the correct directory with the test
file.
Is there some path that has to be set so that Node can find the test
file, and how do I get rid of the "undefinded" replies?
Node looks very interesting, but until these issues are resolved, I
cannot move on, and would be most grateful for some help.

You need to run "node.exe helloworld.js" from your Windows command prompt rather then the REPL that node.exe on its own gives you.

You are seeing "undefined" when you enter a statement that does not evaluate to a value; "undefined" is saying there is no value to display.
Good luck!

OK, many thanks, I tried that out and it works!
I knew it must have been something very simple that I was missing, but
wish the documentation had been a bit clearer.

Many thanks indeed for the links to the documentation, and I just
managed to get a simple example of a web server to run.

Great!
A jump, but interesting (it works on Windows out of the box) to show the power of Node! ;-) to impress your boss or a .Net developer audience:
In any directory, run:
npm install -g jake geddy
The -g flag indicates a global install (your directory is not affected)
From a working directory, then run
geddy app todo_app
A new directory was created
cd todo_app
geddy
Node ecosystem is full of such surprises ;-)

Nice to see two c# devs, Angel and Graeme, answering to guy nick named Csharp, Angel sending links to my friend and coworker Gustavo (also c# dev) and then the icing on the cake, another csharp-er to *notice all this :)
maybe in few months we can beat phpers in node.js :P

Fantastic, now I have another interesting link - many thanks!
As it happens, I just fired off an e-mail to a friend who is involved
with programming mobile devices.
Less than 24 hours ago I hardly heard of server-side JavaScript, and
had never heard that node.js even existed. It was through looking at
HTML 5 and links on writing games with JavaScript that I came across
all this.

Ah! Games!
Related to Azure, but it could be adapted to ASP.NET MVC + Node.js:

OK, lots more information, many thanks.
I've just tried to script a script, i.e. get node.js to generate a
page which includes client-side HTML and JavaScript, with the
client-side JavaScript using AJAX calls, but it does not seem to work
properly. I know the AJAX works correctly on its own using the
docroot container in Glassfish.
Incidentally, I own the domain name csharp.com, but missed getting
csharp.net when it became available.
