I use vibe.d and very little JS (mainly my own) for new projects. 
If I do something with vibe.d instead of JS it's infinitely more 
elegant and efficient. But you cannot do without JS. Sometimes 
it's handy, sometimes it's easier to change things on the fly, 
you can include things with a simple reference to a script etc. 
But heavy reliance on JS is a recipe for disaster. Not only does 
your code become unmaintainable, you always have issues with 
different browsers (mobile vs. desktop etc.)
