Kotlin is a modern programming language initially created as a "better Java." However, Kotlin provides not just a better syntax but also a ton of new interesting features. In this session, you will learn about the subset of the lesser-known features that might not be immediately useful and look obscure at first sight. How does the reified keyword in Kotlin work? What is the difference between inline and crossinline, and why is noinline required? What's the deal with context parameters, and what's the lambda with the receiver? After this session, you will have an idea about the hidden Kotlin features and when to apply these features.
