Makes sense, of course, as the UI is HTML/jqueryUI, binding is knockout and he uses qunit for testing, ninject for IOC etc. but I am still new to this and suddenly it hit me that an ASP .NET web api site could rely almost entirely on things other than C#.

Yeah, but I still agree with most DBA hard hats that validating table data HAS to be done at the db level,
at least if the data is important. As the perf nut in me also sympathizes with having client side validation,
this currently means still double code - having SQL server execute SPROC calling out via Dotnet into JS
might be not considered "enterprize level"...

I am still unconvinced that the MS single direction of layer communication,
which is IMO the crucial difference of MVVM (although it shoud be spelled V-VM-M)
compared to MVC is not the better architecture even for web design.

yupp. we all to often forget the warts vfp for instance has from its heritage...

in the last years JS and python implementations are NOT back ports of Java libraries any more,
and the brevity and clearness possible with interpreted/dynamic typed code is a blessing when debugging.
