Question

I’m trying to get a value from a Redis database. Code:

                                    callback(null, 'Please enter PIN.');
                                    read = db.get(cmd + ':pin');
                                    console.log(read);
                                    n = db.get(cmd + ':name');
                                    waitingType = 'pin';
                                    wait = 1;

However, when I console.log(read) I get true. Why don’t I get the value of db.get(cmd + ':pin')?

Answer 1

db.get is asynchronous, so the db call isn’t done yet when your program reaches the console.log( read )
