A programming language is just an abstraction (built on other abstraction, typically) of turning transistors on and off. JavaScript is most often run in a runtime like v8, but you could build alternate runtimes or event a compiler to target some VM bytecode or an architecture. One of the things that makes interfacing with hardware (as a software engineer) joyful is having your toolsets match your expectations and mental models of how you want your solution to work. JavaScript was built as a language for interfaces and what is hardware? It’s a physical interface. I personally don’t find it totally unsuited for microcontrollers.
