It's such a dream state of JavaScript, that people spent countless of time trying to structure these new web applications in a way so that when one function fails for one button or whatever, it doesn't break the entire client-side view, because that'd be horrible.

So what did the frameworks do? Of course wrap the entire application in one big try/catch, that then changes the entire page as soon as there is any error, instead of presenting users with the information that did load properly. Talk about undoing what the platform and language gives you for free...
