It combines object-oriented and functional programming features. It is focused on interoperability, safety, clarity, and tooling support. Over 80% of the 1000 most popular Android apps currently use Kotlin.
One of its primary features is effective programming—it provides many ways to reuse code between multiple platforms.
Kotlin's clean language design and powerful features offer an accessible user experience. Rather than introducing new concepts, Kotlin brings together programming language features that have proved to be beneficial for large-scale projects for some time now.
Because of its adaptable framework, Kotlin has garnered many users worldwide.
