Electron for Desktop Apps

I've recently started learning Javascript after a long break, one of the tools I put together for myself is what I'm calling blokz-play, which is an electron app running runkit as seen below. Please note that the gist link below can also be used as a standalone.html file as its not just for use in the Electron App, which is just something I find useful.

Source for index.html for use in the Electron Quick Start is at the gist below
