Does Sinuous use VDOM rendering?
No, Sinuous doesn't use VDOM in the classical sense. Only the map
module performs a diffing algorithm that is somewhat similar.
For the dynamic parts of the view Sinuous makes use of a simple but powerful observable which enables fine-grained updates in the exact precision that is defined in the view. This way only the parts that change are evaluated, there is no need to compare whole DOM trees.
