Kotlin is a multi-platform language that is gaining popularity. It is concise, elegant, expressive, and a pleasure to program with. In this presentation we will dive into the exciting features of Kotlin, what makes this language special, both from OO programming and functional programming points of view. We will then take a look at what makes Kotlin a nice language for creating internal DSLs. Finally, we will see how Kotlin coroutines support elegant way to program asynchronous applications.
Language Paradigms are intriguing, some languages are pure and enforce a particular paradigm, and yet some languages are hybrid. A single paradigm language is consistent, easier to use, and often favored by the proponents of the promoted paradigm. Hybrid languages often appear confusing, seem harder to use, and yet there are so many of them. From the programming point of view should we stick to one paradigm or should we dabble into the mixed paradigm arena? It turns out, that is not an easy question.
There are many reasons to adopt functional style of programming. One often touted reason is that it is better for concurrency. While that's true, a more important reason is that functional style being declarative in nature reduces accidental complexity in code. In this presentation we will dive into the essence of functional programming and see how we can make use of it in Kotlin.
