What are the real-world benefits of declarative-UI languages such as XAML and QML?

Question

I\'m currently evaluating QtQuick (Qt User Interface Creation Kit) which will be released as part of Qt 4.7. QML is the JavaScript-based declarative language behind QtQuick.

Answer 1

The point of declarative coding, i.e. WPF or QTQuick is to provide a separation between the developer and presumably the artist that is implementing the visual aspects of your application. With regards to WPF, I find that debugging gets to be a bit harder. As we speak, I am compiling the latest QT to look at QTQuick. (It takes a long time and I have time to look at stackoverflow :-) ) So, I don't have an opinion on that yet.
