Learn Golang Go Tutorial

Learn Golang is an offline Go programming tutorial app for beginners and working developers alike: 69 lessons across 15 chapters, from your first Go program to goroutines, channels and generics.

WHAT YOU LEARN
Every chapter builds on the one before it, and every lesson carries runnable Go code:
- Getting started: what Go is, your first Go program, comments, the fmt package
- Variables and data types: declarations, strings, type inference, iota
- Control flow: if/else, switch, for loops, defer, panic and recover
- Functions: parameters, multiple return values, closures, recursion
- Arrays, slices and maps
- Structs, methods and interfaces
- Pointers
- Error handling the Go way
- Packages and modules
- Concurrency: goroutines and channels
- Testing Go code
- Building a REST API with Go
- Generics

HOW YOU PRACTISE
- Interactive coding exercises: multiple choice, fill in the blank, output prediction, bug fixing, and writing Go code yourself
- Typed answers are graded against the reference solution, with an explanation and a hint when you get it wrong
- Chapter quizzes: a quiz closes each of the 15 chapters
- Flashcards built from every chapter for fast revision
