A modern programming language that makes developers happier.

kotlinlang

do you know a nice kotlin executive advertisement? i dont need detailled technical stuff but a nice sheet which displays how kotlin is vastly superior on efficiency to the martyrum that is terrible java

that's what I need too.. Kotlin for Android and Kotlin for Node.js backend.

you might find something like that in the original 1.0 release announcement
<https://blog.jetbrains.com/kotlin/2016/02/kotlin-1-0-released-pragmatic-language-for-jvm-and-android/>

nothing eyecatching and it doesnt deliver the urgency to switch from java to kotlin at all

I agree, jetbrains could definitely market kotlin better. That would be helpful for adoption.
