delivery as applying during a stable connection, and note that reconnect replay
may deliver a message again with the same timetoken.

Bound the example and clean up on every completion path.
pubnub.publish() can reject before onMessage runs. The suggested catch handles that path, but a successful publish does not guarantee message delivery. Without a timeout, the example can wait indefinitely with its subscription and client active. Route publish failures into one bounded wait, then perform cleanup in finally.

| ## Delivery | ||
|
|
||
| Live delivery through PubNub SDKs is at-most-once. A subscriber can miss messages if its buffer overflows or if it is disconnected when a message is published. For recovery after longer gaps, see [Message Persistence](https://www.pubnub.com/docs/sdks/javascript/api-reference/storage-and-playback). |

Qualify the at-most-once delivery statement.
Line 106 does not limit the guarantee to a stable connection. After reconnect, the SDK can replay a message with the same timetoken, so a handler may receive it again. State the stable-connection qualification and mention possible replay after reconnect. (pubnub.com)
