Introduction

The ability to write code in a way that is easy to maintain and iterate on is a vital skill for an engineer. This means crafting it so that it may be reused, easily expanded upon, and understood by others. Go makes it easy to keep code clean and readable, and separate logical chunks together. The first major way of writing code that is easy to reduce, reuse, and recycle is through the use of functions.

Functions are a core part of many languages and Go is no exception. A function is a section of code that has been declared to perform a task. Go functions can have zero or more inputs and outputs. One feature that sets Go apart from other programming languages is the multiple return values; most programming languages are limited to one return value. This leads into Go’s flexibility and the ability for developers to continuously write adaptable code.

In the following section, we will see some features of Go functions that differ from other languages, such as...
