It seems like my callback is not hitting, am not getting any output on my console.
can you please look into it and let me know if there is any issue in my code or what .

Node version am using : 4.0.4
My code:

function getUserProfile(userId, cb) {
    let redis = redisConnect();
    redis.hGetAll( userId, cb);
}

getUserProfile("teams:91, (err, results) => {
    if(err){
        console.log(err);
    }
    console.log(results);
})

as of 4.x the library uses promise base methods iso the callback variants from before.
More info at https://github.com/redis/node-redis/blob/master/docs/v3-to-v4.md

Is there still traditional callback support that isn't implemented over the new [promise by default] implementation? I noticed the v3-to-v4 docs states "Node Redis now uses native Promises by default for all functions." Suggesting the default can be configured?

you can use 'legacy mode' according to this https://github.com/redis/node-redis/blob/master/docs/v3-to-v4.md#legacy-mode
