🎉 congrats to the kotlin team & community for this release and specially for moving KMP to stable

I read the documentation first and went through the rabbit hole of WASM and WASI and even made some trial runs of the github project kotlin-wasm-examples. This video is exactly what I needed to complete the picture of the full changes. Thanks for the complete delivery of all features for Kotlin 1.9.20. It trully helps to better understand the new features. Btw, I made trials with a madeup program in kotlin of about 6 KLOCs. I didn't measure 2X faster compilation times, but I guess that 2X faster is like the maximum performance we can expect from K2 in comparison to K1. I did measure about 1.5 faster compilation times, sometimes more, sometimes less but I'm convinced. Great that Kotlin only keeps getting better. Love the development of this. Thanks for the video! 👍

Great to see Multiplatform going Stable! Congrats

[EzequielRegaldo]

Congrats ! I want to see (if its possible) a web project written with JS/Kotlin, i'm too hyped. I really enjoyed Kotlin in every aspect, first time im feeling confortable with new tooling. Good job guys !

I was waiting at least in the end the speaker would give a smile 😊
Congratulations on stable release 😉🎉

KMP is stable cool When compose multiplateform ?

[arseniykucherenko]

When KMM will be directly interoperable with Swift without using Objective C as intermediate, it will alleviate challenges such as differences in handling generics, coroutines, ranges, flows, types and sealed/enum classes between Kotlin and Swift. This interoperability will enable developers to more naturally bridge Kotlin shared logic with Swift.

Do I have to learn Java first to learn Kotlin, or can I just learn Kotlin straight away?

[polarnight-no]

Really interesting. But is it really necessary to have music in the background while Anton is talking? It is very distracting when I listen to the video with headphones.

It's time for 1.10 admit it you're not ready for 2.0 lol.

Stop wasting money on developing KMP. Just copy Flutter architecture and render directly to canvas.
