console.error() provides comprehensive error logging: 1) When passed an Error object directly, it automatically logs both the error message and the stack trace, 2) This provides the complete context of where the error originated, 3) The stack trace shows the call path that led to the error, including file names and line numbers, 4) This is much more useful for debugging than logging only the error message, 5) While console.trace() exists, it prints the current stack trace rather than an error's trace, 6) The correct approach would be: console.error(error) or console.error('Operation failed:', error), 7) Modern browsers format Error objects in the console to make the stack trace easily readable, 8) This complete error information dramatically speeds up the debugging process by showing exactly where the error originated.
