Kotlin in the real world

Use Kotlin for Android, backends and multiplatform.

📖 Key ideas

  1. Android: Jetpack Compose UI and coroutines.
  2. Backend: Ktor or Spring Boot with Kotlin.
  3. Build with Gradle Kotlin DSL (build.gradle.kts).
  4. Test with JUnit 5 and kotest; mock with MockK.
  5. Kotlin Multiplatform shares logic with iOS.
💡 Real-life example: Kotlin is a multi-plug adapter: the same skills plug into phones, servers and desktops.
