console.warn() is specifically designed for warning messages: 1) It displays text in a yellow color with a warning icon in most browsers, 2) It visually distinguishes warnings from regular logs and errors, 3) Warnings indicate potential problems that don't necessarily break code execution, 4) Unlike console.error(), it conveys issues that aren't critical failures, 5) These messages appear in the console without stopping program execution, 6) Many DevTools allow filtering specifically for warnings, 7) It provides a stack trace in some browsers for easier debugging, 8) This makes it perfect for highlighting deprecated features, performance concerns, or unusual but non-fatal conditions.
