The watch runs ECMAScript 5.1, but with various extensions (mainly, I think, related to class and async).

I suspect that the companion runs within a WebView component which is maintained by the operating system, so it may be able to run more up-to-date code.

The SDK itself uses whatever version of node.js you've installed.

I think I recall reading that Fitbit OS uses "JerryScript" but I'm not sure if that's still the case. It is indeed based on ECMAScript 5.1
