Today I’m reviewing the course: “Kotlin Koans” published on kotlinlang, it’s free and you can find it in the official Kotlin website.

🍩Would you care about buying me a coffee? You can do it here: but If you can’t that’s ok too!

🙏It would be nice to subscribe to my Youtube channel. It’s free and it helps to create more content.
