Lately I have being struggling with an implementation differences of host (DOM) objects across the browsers. So far only reliable way I could find to identify host objects is by a following assertion:
object.constructor.call === void(0) Behaviour seems to be consistent across FF, Opera, Safari, and Chrome (Don't have windows to test on IE). I think it would be great if there was some standardised way to identify host objects. My personal use case is polymorphic method dispatch library https://github.com/Gozala/method that has same semantics as clojure protocols. Method implementations for host objects and built-ins are stored in the separate dictionary to avoid memory leaks and to support objects from diff JS contexts / frames / compartments. If you know of a better of identifying host objects I would really love to know that too. Regards -- Irakli Gozalishvili Web: http://www.jeditoolkit.com/
