Generics Exercises

Generics Exercises

Practice using Go’s generics with type parameters, constraints, and generic data structures.

Exercises in This Section

Exercise	Difficulty	Time	Description
Generic Functions	Easy	15 min	Write generic utility functions
Generic Data Structures	Medium	25 min	Implement a generic stack and queue

Key Concepts Covered

• Type parameters: Defining generic types and functions
• Constraints: Restricting type parameters
• Built-in constraints: any, comparable
• Custom constraints: Creating interface constraints
• Type inference: When Go can infer type arguments

Prerequisites

Before starting these exercises, you should be comfortable with:

• Go interfaces
• Structs and methods
• Chapter 13: Generics

Tips

1. Only use generics when you need them - simple functions are clearer
2. Prefer constraints over any when possible
3. Consider if an interface would work just as well
