== Why is this an issue?

include::../description.adoc[]

=== Code examples

The following noncompliant code:

[source,javascript,diff-id=1,diff-type=noncompliant]
----
function doSomething() {
  // ...
  console.log("My Message");
  // ...
}
----

In `Node.js` could be replaced by the `winston` logging library:

[source,javascript,diff-id=1,diff-type=compliant]
----
const winston = require("winston");

const logger = winston.createLogger({
  level: "debug",
  format: winston.format.json(),
  transports: [new winston.transports.Console()],
});


function doSomething() {
  // ...
  logger.info("My Message");
  // ...
}
----
