NodeJS Redis Client Returning Wrong Value

I'm using the NodeJS Redis client (Node Redis) and calling the SISMEMBER Redis command. However, when I call the command it always returns true, no matter whether or not the value is a member of the set.

I am using this in conjunction with the Node IRC module. I am at a loss for why the Redis call is returning the wrong value. I have tried isolating just the Redis code (without the surrounding code) and it works fine. Code follows, thank you for the help.

This does not work

var redis = require("redis");
var redisClient = redis.createClient();

ircClient.addListener('join', function(channel, who) {
    console.log(redisClient.sismember('visitedUsers', 'awdwf'));
    console.log(who + ' connected');

This works, however

var redis = require("redis");
var redisClient = redis.createClient();

console.log(redisClient.sismember('visitedUsers', 'awdwf'));



redis methods are all asynchronous. The return values are just booleans indicating whether any more commands should be issued for the time being (depending on if the command queue size exceeds the high water mark -- this is similar to node's stream.write() returning false).

Try something like this:

client.sismember('visitedUsers', 'awdwf', function(err, reply) {
  if (err) throw err;
