Either give me a brand new browser VM with a brand new modern language that is supported by all browsers or don't bother. If my code will be translated to Javascript I rather write it in Javascript and control it myself.
I'll happily adopt a new browser language if it offers me benefits that I don't get from Javascript, but I really don't get the new trend of compile to Javascript languages.
