The entire purpose of using redis with node.js is that it's asynchronous. Asynchronous means that you cannot do something like the first, and that's a good thing.

Your options are: do whatever you want to do with the value in the callback or... no, just do it in the callback.

Btw: That your last way works, is a bit lucky because if the redis-server takes just a little longer, "somevar" will still not be "value" by the time you get to the sys.puts().
I suggest that you read up a little on what it means to work in an asynchronous environment. That should clear it up.

You should always handle I/O responses in the callback..

redis.lindex('mylist', 0, function (err, value) {
    if (err) { throw err }
    sys.puts(value);
});

Thank you both for the responses. I shouldn't have posted example 1, I know that won't work. And now I understand why the other two won't work. I think what drove me towards these examples is that I tried this:

redis.lindex('mylist', 0, function (err, value) { sys.puts(value); });

And it wouldn't put anything to the console. It seemed no matter what I did, value wouldn't give me anything unless I first assigned it to another var, which seems ridiculous. I will try it again when I get home, but I'm 99% sure this was not working for me. And yes, there was something in the DB. Thanks again.

Wow, maritz and marcuswestin beat me to it! Thanks.

@wormwoodmedia: take a look at the test/test.js file for lots of examples.
