Introduction

Hello, coder! Today, we'll dive into the world of Function Overloading in Kotlin. This versatile technique is a powerful tool in Kotlin, allowing us to maintain backward compatibility when introducing new features, much like adding a horn to your toy car while ensuring it still moves forward, backward, and turns around.

In today's lesson, you'll explore:

  • Understanding the concept of Function Overloading in Kotlin.
  • Using function overloading to maintain backward compatibility.
  • Applying function overloading to solve practical problems.

Let's jump in!

Understanding Function Overloading

Our first step is to explore function overloading. Similar to how our bodies react differently to various stimuli (like shivering when it's cold or sweating when it's hot), function overloading in programming allows a function to change its behavior based on different inputs. In Kotlin, function overloading is accomplished by defining multiple functions with the same name but having different parameter types or counts. Consider a greet function that initially just greets a person by name. Later, we may want the option to include a message if needed:
