Does IE9 support console.log, and is it a real function?

Question

In which circumstances is window.console.log defined in Internet Explorer 9?

Even when window.console.log is defined, window.console.

Answer 1

A simple solution to this console.log problem is to define the following at the beginning of your JS code:

if (!window.console) window.console = {};
if (!window.console.log) window.console.log = function () { };

This works for me in all browsers. This creates a dummy function for console.log when the debugger is not active. When the debugger is active, the method console.log is defined and executes normally.
