Not sure I'm using it for anything special... But one reason I chose it is my preference for minimal syntax, which is not a fashion thing and has not changed since I did Python 8 years ago. It also fixes some bugs in JS, like defaulting to globals on omitted `var` or implicit conversions on `!=`.

I do wish to have gradual static typechecking available though. This may unfortunately force me over to TypeScript or ES2015+Flow.
