Interfaces Tutorial - Polymorphism & Type Assertions | Learn Golang #17

Master interfaces in Go! Interfaces define behavior contracts that enable polymorphism and flexible code design. This tutorial covers interface basics, implicit implementation, type assertions, and the Stringer interface. 📚 What You'll Learn: • How to define and implement interfaces • Implicit implementation (no "implements" keyword) • Polymorphism with interface parameters • Empty interface and type assertions • Type switches for multiple type checks • Stringer interface for custom formatting ⏱️ Timestamps: 0:00 - Introduction 0:27 - Interface Basics 2:48 - Interface Polymorphism 6:19 - Empty Interface & Type Assertions 9:07 - Stringer Interface 12:24 - Recap 💻 Code Examples: https://github.com/GoCelesteAI/go_interfaces 🔗 Full Playlist: Learn Go Programming https://www.youtube.com/playlist?list=PLrDePfUQDVTEj-lT6qDBJ-E3KI9LhoEBD #golang #programming #tutorial #interfaces #golangtutorial #polymorphism
