 One of Kotlin's key features is https://kotlinlang.org/docs/reference/null-safety.html[null-safety] - which cleanly deals with `null` values at compile time rather than bumping into the famous `NullPointerException` at runtime. This makes applications safer through nullability declarations and expressing "value or no value" semantics without paying the cost of wrappers like `Optional`. Note that Kotlin allows using functional constructs with nullable values; check out this http://www.baeldung.com/kotlin-null-safety[comprehensive guide to Kotlin null-safety].
