Error monitoring in the browser is a thorny problem. On the one hand window.onerror will at least notify you when something goes wrong, on the other, it won't give you enough information to actually debug the problem! Notably absent in many cases is the stack trace. In this talk, I’ll explain how with a little bit of work, it's possible to get stack traces that are reasonably complete in all browsers, even IE.
