I’ve been developing with Kotlin for the past two years, and when I was asked if I’d like to attend KotlinConf 2019 with some of my colleagues, my answer was a great, big Y-E-S!

Having the chance to attend what is one of the best conferences for mobile devs, I really want to share with you all my overall experience, impressions and feedback from the talks that I attended.

There were 4 different tracks of talks so obviously I couldn’t go to them all, so do check out any of the topics that interest you and that are not covered here. Hopefully, this should make you want to check out the others on JetBrainsTV channel and why not come to the 2020 one? …

Practically speaking, my colleagues and I often need to test an idea as fast and as simply as possible. There’s no point spending lots of effort on implementation because we know that if an experiment proves unsuccessful, we are going to jettison the code in question.

Here I will be showing you, based on real examples, what our approach is in such circumstances and principles to help you select one solution over another. Analysis of these examples should help you to understand how we think, and especially how shortcuts can sometimes be found that speed up development.

I will explore 4 main…

Haskell is an entirely functional and extremely concise language. Anyone who has ever tried to write code in Haskell will notice how much more concise and elegant it is than writing the same thing in an imperative language. In my view you cannot achieve the same results in Java, but Kotlin allows you to make progress in this direction and to try out an entirely functional style for yourself.

You can produce more complex ideas and features, by implementing to your basic function the 3 best-known functions; the ones that people get to know right at the start of studying any functional language: map, filter, and reduce.
And last but not least, I have create a repo. You can clone and check the tests to see how it works. …
