I can see this being a great way to get people interested in embedded devices through a low-friction entry into that world. Hoobyists more likely to be skilled with js than with C so getting them into the IoT world has to be as painless as possible. I see this as also a valid reason for micropython - bring the web programmers into the IoT/Maker world gently. Eventually everyone will realise when they need to do something serious that one can use these other tools to create, experiment, and refine a concept. But when it comes to building something that you want to deploy inside an elevator, car, factory, or bury 10km underground and must work for weeks/months reliably, then most everyone turns to C.
