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:    • This is your last video about Golang ...   📝 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. ⏳ Timestamps: 00:00 - Definition of defer 00:35 - Why interfaces are important 01:42 - Practical example of interfaces 08:38 - The interface type 11:33 - Interface composition 14:29 - Errors and interfaces 17:22 - Outro 👋 Hey there! If you are new to this channel: Hey 👋 my name is Flo and I am a professional software engineer with a passion for coding in Golang, TypeScript, JavaScript, and Rust. This channel is where I share that passion and dive into the exciting world of software engineering. Plus, I love using Emojis and paper-based animations (so have a look for that, if you want to find my videos). 📨 Support and Connect! Buy me a coffee: https://www.buymeacoffee.com/florianw...
