In this episode, Donn talks about Kotlin Lambda Expressions. He explains the syntax and how to build a couple of simple lambda expressions with and without type inference and declaration. We wrap up with a small example of passing a small lambda with multiple values to a function. See the show notes below for more info. This is part 1 of a multi-part series on Lambda Expressions in Kotlin.
In this episode, you’ll learn all about Kotlin Sealed classes. Donn walks you through what they are, how to create them, how to use data classes, objects and regular classes to create a restricted type hierarchy.
Another Learning Kotlin episode. We talk about Returns, Jumps & Labels!
In this quick fragment, Kaushik talks about the new Kotlin 1.3 experimental feature “inline classes” and how it helps with Type driven design.
In this fragment episode, Donn talks about Kotlin extension functions. He discusses what they are, how to build them, why they’re useful, how to organize them, visibility and how to call them Java and much more.
In this episode of learning kotlin, we look at 3 important keywords – inline, noinline and crossinline. The inline keyword is super common and you’ve probably run across this one at some point. What does it mean and when is it useful? We also look at the related but seldom used variants noinline and crossinline.
In this episode of Fragmented, we go back to learning some Kotlin and look at the Iterable like data structure introduced called “Sequences”. What is a sequence? How is it different from Iterable? When should I use it?
Another day, another opportunity to learn more Kotlin. In this episode, Kaushik walks through the concept of visibility modifiers. How do the modifiers in Kotlin differ from the ones in Java? What is this new internal modifier? When should I use each of the operators?

In this second episode of our learning Kotlin series, we talk about Kotlin’s support for static members or … lack thereof. Kotlin as a language was designed so that there’s no such thing as a “static member” in a class but there are times when having static members can be useful.
So what do we do in those cases? do we just avoid static members? are there better alternatives? what are the costs with some of these approaches?

In this mini Fragment, KG talks about his journey learning Kotlin as a newb. Given that Kotlin is most likely going to be the de-facto language for most developers, it makes sense to deepen our understanding of the language (as we have strived with Java over the years).
“Properties” in Kotlin are a first class language feature. But what does that actually mean? What are the nifty features we get with properties? How are these resolved from a Java class when there’s potential a name clash? What are some other gotchas and learnings from using properties? Listen on to find out:
