I applaud this effort and it is a step in the right direction for JS app error tracking, but it is a half-measure: we need to get to the point where frontend frameworks track this by default, post back to a common server endpoint, and then that error report is emailed to the dev/admin list
That does not make any sense. I don't expect Angular, for example, to tell me when I have a syntax error. Also, things are rarely so clean in browser-land, anyway. Just because you have a framework doesn't mean there's not another parallel framework on a page, or plugins that don't need a framework, etc.
