After programming in Java and Scala for many years, I found a best-of-both-worlds language in Kotlin. Luckily enough I was able to work with Kotlin quite extensively, during projects and trainings. While doing that I stumbled upon many gotchas that have led to true facepalm and eye-opening moments!
I’ll happily share these (slightly embarrassing) war stories in this talk. To keep things fair, I’ll put your knowledge to the test: May the best Kotcha spotter win!
