That's not entirely correct - you also must write C code. You can write JS that runs on the phone and can do stuff like call web services, store data, and communicate with the watch. But it's old fashioned C code that you need to have running on the watch in order to render stuff, get sensor data, or exchange messages with the JS running on the phone.

That's not true, you can write a basic app with a UI entirely in JS. I have done this to have control over some home automation bits and bobs.
