Kotlin - Ready for Production
summary
Kotlin reaches 1.0 after ~6 years of development and ships with 20+ JetBrains developers and 100+ GitHub committers, running on the JVM and JavaScript backends with Java 6 compatibility. The language demonstrates concise features (data classes, top‑level functions, extension and delegated properties), explicit nullability with ? and Elvis handling, Android extensions that replace findViewById, Spring Boot support, and a Gradle‑style Cobalt build option; JetBrains uses it in ~10 products and reports 14,000+ active users internally.
