Example using q promise.

        console.log("I will tell you the secret in " + secretWaitLength + " seconds");
        setTimeout(function(){
            console.log("All done waiting, I am going to resolve my promise now and tell you the secret");
            deferred.resolve( data + ", you are cute.");
        }, secretWaitLength * 1000);
        return;
