Talk about Web UI Development Work in progress. Wanted to get future along then I am but time doesn't stop. Going to concentrate on Django but all I say is equally applicable to the other frameworks.
Back-end web stacks all very similar. Request in page out. Template based, very easy to produce one One framework is missing - ToscaWidgets Very good support DRY

This are very good. DRY – makes it easy to do a lot of stuff Lots of extensions, make your site look all pretty and stuff, and interactive
Deferring JS loading increase the number of requests but the user doesn't notice Not every one can afoard a CDN
Problem part
Always repeating yourself – cut and paste Integration with the UI and the back-end Cut and paste CSS How much of your CSS are you actually using How much of the JavaScript are you actually using
No best practice for deferrnig doing so – looking at analytic , etc is too low level. You can't debug Knowing what JavaScript / CSS to include in the file is hard and
This means – templates very good at producing HTML content for a fragment of the page. But when the page is returned we may have wanted to add JavaScript and CSS to animate and style the content we just returned. To do this and play nice with best practice in web site performance is hard.
Intentionally left out of the first round of frameworks Resource injection JavaScript calls – integration with framework Researching at the moment Want to get to work with Django
