Messages being published without established connection to broker. What happens to the messages?

[manasatully]

From reading the docs I see that mqtt.Client has this feature that automatically happens - start publishing before being connected.

In my code I am creating a connection using myclient = mqtt.connect({...}) function. With the client that is received I have a call-back setup for connect and end. I am reading messages from a queue and publishing them by calling myclient.publish()

I see that the connection has not been established and the publish function is being called inside the for loop. I see that my for loop is not erroring out causing all messages in queue to be consumed. Since there does not exist a connection to the broker what would happen to the messages (since the client supports publishing messages to broker even before being connected)? Would they be sent when a connection is re-established/ I would lose the messages all together?

`
myclient = mqtt.connect({...});

myclient.on("connect", () => {
console.log('Connection established to broker');
});

myclient.on("error", (error: Error) => {
console.log(Encountered error ${error});
});

for (const message of messages) {
myclient.publish(mytopic, msg);
}
