consoleSpaces

Disallow leading or trailing spaces in console method string arguments.

✅ This rule is included in the node stylistic and stylisticStrict presets.

Leading or trailing spaces in console output are often unintentional and can make debugging harder. They can be difficult to spot in console output and may lead to confusion about the actual content being logged.
