Return in Kotlin Functions
Last updated
What is Return in Kotlin Functions?
In Kotlin, the return statement is used within a function to stop its execution and send a value back to the caller. The value returned must match the function's declared return type. If a function doesn't explicitly return a value (its return type is Unit), the return statement is optional at the end of the function; otherwise, it's required to provide a value of the correct type.
