Hey guys!
Is there somewhere that contains short descriptions of Kotlin concepts?
I want to explain !! to a Java developer that will start working with Kotlin. I wanted to do it in a succinct way that I can send as a slack message without being too boring.
A longer cheatsheet or glossary is probably what I'm looking for, but I couldn't find it yet.

Looking for something like this?

https://kotlinlang.org/docs/keyword-reference.html#operators-and-special-symbols

[Matthew Gast]

Also, that particular operator is covered quite succinctly in the null safety section in the documentation: https://kotlinlang.org/docs/null-safety.html#the-operator

[LeoColman]

Yes! The operators-and-special-symbols cover a lot of what I could think!

This is a nice cheatsheet I used to hang at my work desk https://kt.academy/Kotlin_Cheat_Sheet.pdf
but it doesn’t cover !! and other stuff.
This one from Dzone is longer but covers pretty much everything: https://dzone.com/storage/assets/9054799-dzone-refcard267-kotlin.pdf
