Golang: The Last Interface Explanation You'll Ever Need

Interfaces are common, easy and important to use in Golang. Next to interfaces, structs are also really important. I've also made a video about them, so feel free to check out this video as well: https://youtu.be/c8H0w4yBL10

📝 Description

This time we're tackling interfaces, a vital component of Go and a must-have in every Go developer's toolkit. We'll start off with the basics of defining and implementing interfaces and move on to more advanced topics like implicit interface implementation, the empty interface, and type assertions. We'll also explore the practical application of interfaces through a use case involving a Shape interface with an `Area()` method. This will provide a clear demonstration of methods attached to structs.
