I've never heard of repl.it, but the concept reminds me of a project that uses a Javascript REPL/IDE to try to make embedded development more approachable called 'Espruino': https://www.espruino.com/ide/ https://www.espruino.com/ide/ It's nice for learning, because you can get the immediate feedback of a terminal with physical hardware. It is extremely limiting in that you can only have one file open in the IDE though, so it is unfortunately difficult to justify for anything other than teaching or toy projects.
