In this article, I will show you how to implement enums in Golang using a predeclared identified iota. Before proceeding with enums, let’s first understand what is iota and how it is used.

An enum group related constants together in one type. Enums are a powerful feature with a wide range of uses. However, in Go, they’re implemented quite differently than most other programming languages.

Note: Before you go any further, I expect you all have a beginner-level understanding of Go syntax and primitive types to understand the source-code.

What is iota?

iota is an identifier that is used with constant and which can simplify constant definitions that use auto-increment numbers. The iota keyword represents integer constant starting from zero.
