JavaScript console Polyfill / special case pattern. Basically prevents cross-browser console hell by implementing missing console and empty methods so no JS errors will occur. I found this useful and decided to post a gist. There are many versions of it in the wild; this is only one.

gistfile1.js

// Run this script before any others.
// Polyfill: provides a missing console and empty implementations for its missing methods. 
(function(disable) {
	if (!window.console) window.console = { };
	var methods = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml", "group", "groupEnd", "time", "timeEnd", "count", "trace", "profile", "profileEnd"];
	for (var i = 0; i < methods.length; i++) {
		if (disable || !console[methods[i]]) {
			console[methods[i]] = function () { };
		}
	}
	console.log('console not an issue'); // << remove this line after verification of no error
})(false); //'disable' param: false to fill in only missing methods, true to replace *all* console methods with empty implementations
