Not really, just normal error handling issues like most other languages.
You should always know how the api you are using returns an error and use it - most langauges have multiple common ways of notifying of an error.
As to leaking, coming from Java's terrible error handling, you just start using runtime errors all the time anyway, at least with js the result is more concise.
