> If you have an IoT device and want to share logic between the device and cloud ... You could represent the logic in C but arguably something like JS is better suited

Is this ever realistically the case? JavaScript aside, I would expect there to be an interface layer in the form of some compact protocol (e.g. CoAP) for communication and for the IoT device to be doing as little as humanly possible.

Yes, the parking meter example is an exact case I ran into in real life. But Microvium didn't exist back then.

But in general, an IoT solution may have some business logic or rules that transcends the specific device, and some may prefer to represent that logic in a high level language like JS, and some situations may benefit from being able to access that logic from multiple places -- e.g. front-end, back-end, and device.
