I heard about kotlin long time ago, but I was studying with groovy, scala and clojure.
groovy was still alive and java 8 was coming, I didn't have time for another one JVM language.
but when I spent some time with kotlin, I found there is no reason to code in java anymore, kotlin is more concise and has the same thinking as java.
search my blogs for some random notes, I may put reading notes here when I have time to extract them.
