Go Generics

Introduction

Write reusable type-safe code with generics.

This tutorial explains the concepts and provides practical examples you can run yourself.

What You Will Learn

• Understand the core idea behind go generics.
• See common usage patterns with clear examples.
• Avoid typical mistakes beginners make.

Basic Example

package main

import "fmt"

func main() {
    // Example code for Go Generics
    fmt.Println("Hello from Go Generics")
}

Key Concepts

Go emphasizes simplicity, clarity, and strong tooling. When working with go generics, keep these principles in mind:

1. Explicit is better than implicit.
2. Composition is preferred over inheritance.
3. Errors are values, not exceptions.

Common Patterns

Here is a slightly more advanced example demonstrating a typical pattern:

package main

import "fmt"

func main() {
    result := example("Go")
    fmt.Println(result)
}

func example(name string) string {
    return "Learning " + name + " with Go Generics"
}

Try It Yourself

1. Modify the example to accept user input.
2. Experiment with different values and observe the output.
3. Write a small test for the function you created.

Summary

Go Generics is an essential building block in Go programming. Practice the examples, explore the Go standard library, and move on to the next tutorial when you are comfortable.
