## What it is
A hands-on tutorial repository for learning Go generics introduced in Go 1.18, with labs, benchmarks, and an FAQ. It explains generic type concepts, internals, and practical patterns through runnable examples.

## Use cases
- learn go generics from scratch
- understand how go implements generics internally
- find answers to go generics questions like what any means
- benchmark generic vs non-generic go code patterns
- get started with type parameters in go 1.18

## When to choose
- you are a Go developer new to generics and want guided labs
- you want explanations of generics internals and type erasure in Go
- you need a quick FAQ for generics syntax like tilde constraints

## When to avoid
- you need up-to-date coverage of newer Go releases since the repo was last updated in 2022
- you want a production library rather than a tutorial
- you are not working with the Go language

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation, benchmarking
- domain: tutorials, programming-languages, education
- platform: go, cross-platform
- tags: go-generics, type-system, hands-on-labs, faq
