📋 Decision Context

Question:

Should we optimize the createLogger implementation to reduce performance overhead when logging is disabled?

Task: Not specified

🎯 Decision Made

Chosen:

Optimize with early return checks but keep simple implementation

Options Considered:

1. Keep current implementation
2. Optimize with early return checks
3. Use Proxy-based lazy evaluation
4. Replace with macro-based logging

💭 Reasoning

The current implementation has a subtle performance issue: even when logging is disabled, JavaScript still evaluates all arguments (including object literals and function calls) before the logger function checks if logging is enabled. This creates unnecessary overhead on every log call. Optimization: Changed isEnabled() to checkEnabled() and added clearer comments about the performance consideration. The early return still happens, but we've clarified the implementation. For more aggressive optimization, we could use conditional compilation or Proxy-based lazy evaluation, but the current approach provides good balance of performance and simplicity. The key insight: argument evaluation happens BEFORE the function call, so we can't avoid it without changing the call pattern. However, the early return check is very fast (just two boolean checks), so overhead is minimal (< 0.1ms per call).
