A modern programming language that makes developers happier.

kotlinlang

what about changing the ctachphrase from "Arrow brings idiomatic functional programming to Kotlin" to
&gt; The perfect companion for your epic Kotlin journey
and then below "Inspired by functional, data-oriented and concurrent programming"

(data-oriented is what Java folks seem to be using to refer to data classes + sealed hierarchies)

Sounds good! But I wonder if "epic" is a bit too much? I'd prefer "The perfect companion for your Kotlin journey"
