# Introduction As projects grow in complexity, it is common to divide the code into multiple functions. This approach improves code readability, facilitates collaboration, and allows you to quickly reuse logic without duplicating code. In this lab, you will learn the fundamentals of creating and using functions in Go. You will see how to define your own functions, understand how Go handles parameters and return values, and learn about `init` functions and variadic parameters. **Key Topics:** - Understanding what functions are and how they work - Declaring functions in Go - Passing parameters by value and by reference - Returning multiple values from a function - Using the `init` function to set up your environment - Working with variadic parameters for flexible input handling
