I am wondering about choice of language for me when using Mongoose OS. I have understood that C is generally quicker, which would be relevant for me (and would make me choose C). But I need to send data to Google Cloud IoT Core, which I have managed to do in JS, but not yet in C. In the docs on Google on sending data over MQTT, there is C++ code for doing what I want, and I have understood that C++ is possible to combine with C (using a separate cpp file afaiu?). But would it be faster than JS if I start using C and C++ combined? Is it possible to combine JS and C also?
You can use C, C++, mJS in any combination you want.
mJS: Restricted JavaScript engine
Really helpful, thanks! This is great news.
