The best way to manage our code is to break it down into small, self-contained portions and the complex problem can be solved by putting these portions together. Kotlin can help us to divide our code into small chunks, and we can then assign a meaningful name to our code. That block can perform one particular task for us. In different programming languages, this technique is called a method, subroutine, or procedure. In Kotlin, this technique is called a function.
