Johnny Five doesn't let JavaScript (Node) run on the microcontrollers themselves -- it requires a USB (or serial) link firmware installed in the board.
The program runs on your computer and issues commands to the firmware via the link. This makes the board "tethered" to the PC so to speak.
That said, hooking up a Raspberry PI running node to an Arduino sort of alleviates the "tethered-ness" and I believe it is the lowest effort barrier to entry into robotics and presents endless creative opportunities.
