I think it's kind of nifty, and potentially a nice feature to have.
That said, I don't have anything installed yet that uses it yet (I just got my Bangle2 last week) and might or might not actually end up using it. If support for it went away in the future, I suspect I wouldn't be terribly disappointed.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
