Anonymous Functions in Golang

# Introduction

In the previous labs, you learned how to write and use named functions, how to organize code into modules, and how to improve code readability by splitting logic into separate functions. In this lab, we will explore **anonymous functions**, a special type of function that has no name. Anonymous functions are useful when you want to define a small piece of logic "in place" without having to declare a separate, named function.

**Key Topics:**

- What anonymous functions are and how to define them
- Calling anonymous functions without assigning them to a name
- Passing parameters to anonymous functions and returning values
- Using anonymous functions as callback functions for more flexible code
