Best Practices#
Development:
✓ Use appropriate log levels
✓ Group related logs
✓ Add context to messages
✓ Use console.table for data
Debugging:
✓ Use console.trace for call stacks
✓ Use console.time for performance
✓ Use console.assert for validation
✓ Use console.count for frequency
Production:
✓ Remove or disable debug logs
✓ Keep error logging
✓ Use proper logging service
✓ Don't log sensitive data
Avoid:
✗ Leaving debug logs in production
✗ Logging sensitive information
✗ Over-logging (performance impact)
✗ Using console.log for everything
Conclusion#
The console API provides powerful debugging tools beyond basic logging. Use tables for data visualization, groups for organization, timing for performance measurement, and assertions for validation. Create custom loggers for production-safe logging with appropriate levels.
