Yeah node uses bindings too, examples:

node-llama-cpp (C++)... node-SDL (C)...

Why wouldn't it also be true for mechatronics? Have some native bindings for C libraries then you can write Node or Python and still use the machine code where needed. Speaking of which:

Wouldn't both JIT vs not JIT have an impact on speed, and also some of the "heuristical" stuff V8 does?

I wouldn't rule out JavaScript for mechatronics, everything ends up in JavaScript.
