Internet Explorer: “console is not defined” Error

Question

I was using console.log() in some JavaScript I wrote and an error of: console is not defined was thrown in Internet Explorer (worked fine in other

Answer 1

Some browsers do not have console enabled when the dev-tools is closed. Also, one would encounter this issue with WebViews or iFrames where console is disabled.

The error in these cases is - Uncaught ReferenceError: console is not defined

Inspired by many answers on here, I developed a library for this usecase: 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.
