While logging, now we can log the additional parameters along with the message and severity level. For example,

app.listen(ServerConfig.PORT, () => { console.log('Successfully started the server on PORT : ${ServerConfig.PORT}'); Logger.error('Checking error logging', {msg: 'Something went wrong'}) });
