- * The send, subscribe and unsubscribe methods are implemented as asynchronous JavaScript methods
- * (even though the underlying protocol exchange might be synchronous in nature).
- * This means they signal their completion by calling back to the application,

- * Such callbacks are called at most once per method invocation and do not persist beyond the lifetime
- * of the script that made the invocation.
- *
- * In contrast there are some callback functions, most notably onMessageArrived,
- * that are defined on the {@link Paho.Client} object.

- * @param {string} path - the path on the host to connect to - only used if host is not a URI. Default: '/mqtt'.

- * cause the client to be disconnected. The disconnect call back may be called without
- * the connectionComplete call back being invoked if, for example the client fails to
