I remember once having to write up a significant portion of my old company's UI in the then-hotness, DustJS. Until of course after about a week or two the PM became bored of the idea and we reverted to jQuery+Bootstrap, having wasted a tonne of everybody's time. Perhaps it's my tainted personal experience with JS frameworks, but I simply can't get excited for any 'new thing' in the JavaScript world now.
