That... doesn't change the fact that entirely javascript based applications are a wart on web ? It's very fast and responsive until I want to disable Javascript because I don't want terrible scripts using an entire CPU core to animate your flyout. I don't want to load 20MB of scripts and run them on my machine because the language and platforms you chose are terrible and you needed to fix the shortcomings of Javascript, I don't want your application hitting multiple CDNs telling them where I am (as an example, I do not imply that your application does so). And most of all, I do not want to have to maintain your javascript based software, only held together by all the libraries you used. If you wanted to make a responsive application, you'd have written it in a language that compiles to desktop applications (Java/C#/C++/Python/...). Javascript is the easy way out, where you decide to fuck over your users.
