Learning Kotlin is a pleasant process and only takes a few hours if you’re familiar with the Java programming language. :) The syntax is very intuitive, e.g. a when the block is more readable than an if block or switch. At Netguru, we had quite an adventure with Kotlin over the last few weeks while creating the Coolcal app. Here you can read about how we did it. In this article, I want to tell you more about what it’s like to learn Kotlin.
