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
