Join us on March 19th for the next NLKUG meetup at adesso Office, Utrecht! Enjoy an evening with 2 great talks, networking, and a lively panel discussion on some of the hottest topics in the Kotlin community. RSVP now!

In this meetup, you’ll get a hands-on introduction to Kotlin and discover why it is often described as “a better Java”—and, more importantly, which language design choices make that claim true. Rather than focusing on syntax or language features alone, we’ll explore the core concepts that make Kotlin a safer, more expressive, and more productive language for JVM developers – and AI-coding assistants as well: Null-safety & secure coding by design Immutability-first thinking Expression-oriented syntax Concise yet readable class, collection, and function definitions Functions as first-class citizens Powerful extension mechanisms
