+
+### Console.Info()
+Console.Info method is used to log general information during code execution. This method will log data without interrupting computation. The message logged will be marked as Event Level Informational.
+
+```javascript
+console.info('my info message');
+```
+
+### Console.Warn()
+Console.Warn method is used to log data that may not be correct or expected but are still accepted for computation. This method will not interrupt computation and will resume running after method is return. The message logged will be marked as Event Level Warning.
+
+```javascript
+console.warn('my warning message');
+```
+
+### Console.Error() and Console.Log()
+Console.Error method is only used to log error case where code cannot continue to run. This method will throw exception with the error information provided as input parameter and job will stop running. The error message logged will be marked as Event Level Error.
 
 ```javascript
-console.log('my error message');
+console.error('my error message');
 ```
