How To Use Generics in Go

**How To Use Generics in Go**

The author selected the Diversity in Tech Fund to receive a donation as part of the Write for DOnations program. Introduction Generics in Go let you write reusable, type-safe code that works with multiple types without giving up compile-time checking. You declare type parameters (placeholders for types) and optionally restrict them with type constraints, so the compiler enforces correct usage and you avoid the type assertions and runtime errors that often come with interface{}. In this tutorial you will build a card-deck program: start with a deck that stores cards as interface{}, then refactor it to use generics, add a second card type, constrain the deck to card types only, and create a generic function that works with any card. By the end you will know when to use generics in Go and how type parameters, constraints, and type inference work in practice...
