I wonder the same thing. Writing a scripting language on top of another scripting language makes me wonder, why add another layer? A common complaint I have seen with frontend JS apps is that people tend to unnecessarily bloat them. But I do appreciate the efforts and idea. Most probably the developers must have thought this through and have definitely kept the performance aspect in mind.
