Q

What is the recommended approach for handling console logs in production code?

A). Disable all console logs in production code. B). Include detailed console logs for all scenarios. C). Use conditional logging and minimize excessive logging. D). Log all errors and exceptions using console.error().

Answer & Solution

Answer: Option Option C

Solution:

The recommended approach for handling console logs in production code is to use conditional logging and minimize excessive logging. While console logs are valuable for debugging and monitoring during development, they should be disabled or minimized in production code to avoid unnecessary logging overhead and potential security risks. Conditional logging allows developers to selectively log information based on specific conditions or scenarios, ensuring that only relevant logs are outputted in production environments. Including detailed console logs for all scenarios or logging all errors and exceptions using console.error() is not recommended for production code, as it can lead to performance issues, information leakage, and unnecessary clutter in production logs.
