An Introduction to Kotlin

on YouTube ↗49m

" summary

Claims Kotlin cuts boilerplate and avoids many null pointer errors (cites ~196,000 GitHub null issues and ~15,262 StackOverflow duplicates), is 100% Java-interoperable, and targets JVM/JS/Native; shows concrete syntax: var/val and type inference, safe-call (?.), Elvis (?:) and the !! escape hatch, and data classes, lazy delegates and reified inline generics. Uses IntelliJ, Gradle Kotlin DSL, Spring support, Play.kotlinlang.org and Coursera examples. Demonstrates real multi-platform builds at KotlinConf (Android, iOS, web, backend) and says coroutines replace complex async code.
