Javascript: Overriding Map function

Question

I need to have an object called Map() but it appears there is some function in JavaScript with the same name and when I override it I'm unable to use console (or maybe it's just Opera browser thing). What would be the best way around it? I know I could just use some namespace, but Map is kinda my namespace by itself, so it'd be just too chaotic.

@edit: So I came across this module pattern and I think it may be the best way to use it in my case. Thanks for all the comments anyway.

you can override it, if you must... honestly, just change the name of your 'namespace' & don't fuss. — jeremy

"but Map is kinda my namespace by itself" please stick to the coding conventions in JS. Only classes start with an uppercase letter. — Thomas

@Martin I think what I use is actually quite similar to that. I do UpperCamelCase for classes (or functions that are meant to be used as constructors) and camelCase properties of objects, but I use lowercase_with_underscores for normal variables, UPPERCASE_WITH_UNDERSCORES for constants (whether they are a property of an object or not), and UpperCamelCase for namespaces (I only ever use one root namespace and properties of that object may also be UpperCamelCase subnamespaces). — Paul

@LeszekWiesner, what exactly is your use-case? Maybe you can use a different namespace/name and inject it for example into an IIFE. This way you can use whatever (valid) name you want in your code, and don't have collisions in the global namespace. (function(Map){ /* ... */ })( MyOwnMap ); — Thomas

I would say namespace it or create a name other than Map. It's attached to most browser's window object. It would be dangerous to rename it in case it's a dependency of any package your codebase is using.
