That was coffeescript, but it's come and gone already.

I'd put coffeescript as the "Groovy" of JavaScript.

Kotlin is more like a mixture of Typescript and/or Reason (or whatever the name is now)

Groovy was that flash-in-the pan idea that had some really cool ideas.

But then again, I'm not sure if it really inspired any real language changes to Java like Kotlin has. CoffeeScript did a TON of inspiration for ES6... so heck, maybe Kotlin IS the CoffeeScript

I hope Kotlin survives though.
