Kotlin 102: Beyond the Basics

This talk is about covering language aspects and idioms that you usually don’t see in a 101 talk. Among other things, we’ll understand covariance and contravariance with generics, learn about the secrets of inline functions in Kotlin and how combining them with reified generics we can work around type erasure on the JVM. We’ll dive into lazy evaluation with sequences, use delegation to leverage code reuse and understand lambdas with receivers better to create our own DSL’s.

Finally, we’ll dive into co-routines and see how this powerful concept allows us to deal with concurrency and asynchronous programming, and its difference to languages such as C# or Java.

If this talk is on your list, you might consider brushing up on some Kotlin basics before attending as it’s geared toward an intermediate level. But, by doing so, you’ll walk away with knowledge of some of the advanced features of Kotlin, beyond the introductory level stuff, and see how you can leverage some of the language constructs to create more idiomatic Kotlin code, according to Hadi.
