I am currently working with nodejs application. We use console.log for server side printing purpose, But here logger.log also used. Both will do the same work, but logger.log isn't able to be used more than once in a function like below

logger.log('check level 1')
logger.log('check level 2')

anybody can help?

• Are you using this? If not it looks like you are using another library. Can you hunt it? – David González Commented Jul 7, 2016 at 7:42
• 1 logger.log isn't part of node. You're using a library. Read the documentation for that library. – Mulan Commented Jul 7, 2016 at 7:45
• Even if he's using winston or log4js, I don't see how the logger wouldn't be able to log twice in the same function. – Pierre Arlaud Commented Jul 7, 2016 at 7:46
