Moddable and Espruino have a slightly more restrictive license for when u want to maybe monetize your project. Duktape and Jerryscript are way bigger open-source projects (on github at least). I used almost all of the interpreters to do a hello world on a microcontroller. They all work great! I found Duk to have a slightly cleaner API for bindings, for example writing to the serial port from JS land. https://github.com/svaarala/duktape https://github.com/svaarala/duktape https://github.com/jerryscript-project/jerryscript https://github.com/jerryscript-project/jerryscript
