golings
Learn Go by fixing real code, not by watching videos. Every exercise is broken on purpose and passes only when the tests and the linter agree. No prior Go needed — run any of them in the browser before you install anything.
An interactive Go trainer in your terminal: edit and fix broken exercises with instant test + lint feedback, plus navigation, search, hints, and streaks.
What is golings?
Section titled “What is golings?”golings is rustlings for Go — the same idea, a different language. If you learn a language by debugging it rather than by reading about it, this is the whole course: open the next exercise, make it compile, make it pass, move on.
Nothing to install
Every exercise opens in the Go Playground from the catalog — read it, run it, watch it fail, before you clone anything.
Instant feedback
A terminal UI re-runs the exercise the moment you save, and nothing advances until the tests pass and golangci-lint is clean.
Full language coverage
Errors, generics, the concurrency stack, stdlib and testing — current through Go 1.26.
The path, stage by stage
Section titled “The path, stage by stage”Four stages, in order. You start at var x int and finish with a concurrent
log-ingest service you wrote yourself.
| Stage | What you get | Covers | Topics | Exercises |
|---|---|---|---|---|
| Beginner | Syntax you cannot skip: values, control flow, and the built-in collections. | Fundamentals, Collections & Loops | 11 | 36 |
| Intermediate | The type system Go programs are actually shaped from, plus errors and generics. | Types & Methods, Functions & Errors, Generics & Modern Go, Packages & Modules, Testable Design | 15 | 57 |
