I'm not really sure what it does any better than a Raspberry Pi + LCD shield... It's not significantly smaller, and it's not going to be better supported or have more of a community.
I guess maybe battery life might be better, but even so - it's unlikely to be amazing.
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.
Personally I don't get it at all...
