Kotlin is a programming language that blends object-oriented and functional programming features. On the object-oriented front, it offers support for nominal subtyping with bounded parametric polymorphism, which is akin to generics, and mixed-site variance. In terms of functional programming, Kotlin excels with its robust support for higher-order functions and lambda literals.
