No warn

ErrorRoblox
small-rules/no-warn

Use Log instead of warn().

Rationale

Same reasoning as print(). warn() is just print() with a different output channel: no levels, no filtering, useless in production.

Use Log instead. It handles severity through its API, not through which global you called. Not recommended to suppress this one either.

Diagnostic Messages

noWarn
warn() is a raw output function lacking log levels, timestamps, and filtering. Production systems require structured logging for debugging and monitoring. Replace warn(...) with Log.

Configuration

This rule does not accept options.

Examples

global warn call
warn('Hello');
logger warn call
Log.warn('Hello');
No PrintRelatedSame banned-global factory: raw print/warn output should become structured Log calls.
