Protip: never even mention undefined in your codebase. Erase it from your vernacular. If you ever need to pass or return nothing, you use null.

You probably meant [object Object] :) Since arrays have their own default toString implementation (its own can of worms that is the basis for JSFuck[0]), you'd have to go out of your way with Object.prototype.toString.call to get [object Array]
