A modern programming language that makes developers happier.

kotlinlang

I am building my big project with multiplatform support. It performs very well. Business logic is shared between backend and frontend. It allows me save tons of requests, and code hardest code once. Kotlin wrappers work perfect, they are maintained well. However, I got tons of problems with `kotlinx.serialization` plugin and it is maintained poor :disappointed: Currently I am using my own patched versions of it.

But you have to brace yourself for changes. IMO, guys from JetBrains never break backward compatibility without good reason. So, I could learn a lot of about designing of such systems.
