A MaybeLocal<> is a wrapper around Local<> that enforces a check whether the Local<> is empty before it can be used.
If an API method returns a MaybeLocal<>, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a TerminateExecution exception was thrown. In that case, an empty MaybeLocal is returned.
