JavaScript doesn’t have a few bad decisions baked into it, it’s an absolute minefield. It was made for one thing and one thing only: making simple scripts for web pages. Anything beyond that and it becomes increasingly difficult to maintain. I honesty have no idea why devs are so hellbent on using it everywhere. Putting such an unreliable dynamic language, with absolutely no safety guards when it comes to type checking and serialization, on bare metal hardware is not something I’d ever consider in good conscience. Maybe it could be used for some IoT devices, but that’s it, definitely not for something that interfaces with machinery or anything more than something like a display. TinyGo sounds like an infinitely better pick if someone wants to use a garbage collected language on an embedded device.
