Type Checks & Casts

Kotlin allows you to check the type of a variable at runtime using the is operator. This operator returns true if a variable is of a certain type. Furthermore, Kotlin's smart casts automatically cast a variable to a more specific type within a block of code if the compiler can guarantee that the variable is of that type due to a type check. This eliminates the need for explicit casting in many situations, making the code cleaner and safer.
