Interfaces in Go
Welcome back to the Go From Scratch series! In this episode, we’re diving into interfaces in Go – one of the most powerful features of the language.
Go doesn’t have traditional object-oriented inheritance, but with interfaces, we can still write flexible, reusable, and decoupled code.
We’ll walk through:
What interfaces are and how they work
Implicit interface satisfaction (no “implements” keyword!)
A real-world example using Notifier with EmailNotifier and SMSNotifier
Writing a flexible function that works with any type that satisfies the interface
By the end of this episode, you'll understand how interfaces help Go achieve polymorphism and clean architecture — even without classes or inheritance.
Whether you're brand new to Go or brushing up on the fundamentals, this episode will help you understand how and why to use interfaces in your own projects.
