Q
Which approach is recommended for logging sensitive data using console.log()?

Answer & Solution

Answer: Option Option A
Solution:
The recommended approach for logging sensitive data using console.log() is to use console.warn() instead. While console.log() is commonly used for logging general information, values, and messages, console.warn() is specifically designed for logging warnings and alerts, including potentially sensitive data that should not be exposed in plain text logs. Using encryption algorithms or console.error() may not be suitable for logging sensitive data, as they may not provide the appropriate level of security or visibility for handling sensitive information in logs. It is best to avoid logging sensitive data altogether whenever possible or use specialized logging methods like console.warn() for warnings and alerts related to sensitive data.
