Add functionality of JavaScript errors check to Smart Update

shared this idea
This request has been reviewed. We have doubts that this can be done, because JavaScript is interpreted by the browser, not the server. It is thinkable to develop a software that impersonates a browser, crawls all pages of a website and logs all JavaScript errors and than is intelligent enough to determine which of these errors are critical and which are not. But it is also clear that this would require a monstrous investment into artificial intelligence and backend crawling and cpu power. We are afraid that for a request that only got a single vote during 2 years such an investment cannot be made. For that reason we must decline this request for now. Should new developments rise, there is always a chance to rethink this.
