Javascript - Override console.log and keep the old function

Question

I would like to override console.log and call it on my new function.

I try something like this but I get Uncaught TypeError: Illegal invocation:

Answer 1

I would recommend using: https://github.com/sunnykgupta/jsLogger

Features:

1. It safely overrides the console.log.
2. Takes care if the console is not available (oh yes, you need to factor that too.)
3. Stores all logs (even if they are suppressed) for later retrieval.
4. Handles major console functions like log, warn, error, info.

Is open for modifications and will be updated whenever new suggestions come up.
