Go Tutorial” actually means — and then we’ll walk through the real beginner journey like we’re sitting together with a laptop in Hyderabad ☕
Most people when they say “Go Tutorial” (or “Golang Tutorial”) are actually referring to one of these three famous learning resources:
- A Tour of Go → the official interactive introduction (most popular first step)
- Tutorial: Get started with Go → the official written getting-started guide
- Any general “Go tutorial” (YouTube / W3Schools / GeeksforGeeks / freeCodeCamp etc.)
But 80–90% of beginners mean A Tour of Go when they say “Go Tutorial”.
Let me show you both the most important ones in detail — with real code examples, explanations, and the “why” behind things — like a human teacher would do.
1. What is “A Tour of Go”? (The Famous One)
Link: https://go.dev/tour (You can run every example right in the browser — no installation needed at first!)
It’s an interactive, browser-based tutorial made by the Go team.
- Short slides (1–2 minutes each)
- Code editor on the left
- Output on the right
- You can edit & run instantly
- Small exercises at the end of many pages
- Covers ~80% of what you need to start writing real Go code
It has 4 big sections (2025–2026 version):
| Section | What you learn | Approx time |
|---|---|---|
| Welcome | Hello World, how to run code | 2 min |
| Basics | Packages, variables, functions, types, constants, for/if/switch | 30–50 min |
| More Types | Pointers, structs, arrays, slices, maps | 25–40 min |
| Methods & Interfaces | Very important — Go’s version of OOP | 30–50 min |
| Generics | Type parameters (Go 1.18+) | 15 min |
| Concurrency | goroutines + channels (Go’s superpower) | 30–60 min |
Real example from Tour – Packages & Imports
|
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
// Every Go file must start with a package name package main // This is how you bring other people's code import "fmt" // the famous print package func main() { fmt.Println("Hello, Webliance from Hyderabad! 🇮🇳") } |
Run → Hello, Webliance from Hyderabad! 🇮🇳
Another important one – Short variable declaration (very Go-style)
|
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
package main import "fmt" func main() { // Long way var name string = "Webliance" // Go way (short declaration with := ) age := 25 // type inferred! height, isStudent := 175.5, true fmt.Println(name, age, height, isStudent) } |
Quick exercise style (like in Tour) Fix this code so it compiles:
|
0 1 2 3 4 5 6 7 8 9 10 11 12 13 |
package main import "fmt" func main() { x = 42 // error — no declaration! fmt.Println(x) } |
Answer:
|
0 1 2 3 4 5 6 |
x := 42 // or var x int = 42 |
2. Official “Get Started” Tutorial (Written Version)
Link: https://go.dev/doc/tutorial/getting-started
This one is not interactive — it’s step-by-step instructions assuming you install Go on your machine.
Steps it teaches:
- Install Go
- Create hello.go
- go run hello.go
- go mod init example/user/hello
- Add external module → go get rsc.io/quote
- Use it:
|
0 1 2 3 4 5 6 7 8 9 10 11 12 13 |
package main import "fmt" import "rsc.io/quote" func main() { fmt.Println(quote.Go()) } |
Output: Don’t communicate by sharing memory, share memory by communicating.
This teaches you modules, go.mod, importing third-party packages — very important modern Go.
Quick Comparison – Which should you do first?
| Resource | Best for | Interactive? | Install needed? | Covers concurrency? |
|---|---|---|---|---|
| A Tour of Go | Absolute first step | Yes | No (browser) | Yes |
| Get Started Tutorial | First real project + modules | No | Yes | No |
| Go by Example | Looking up patterns quickly | Yes | No | Partial |
My personal recommendation path (2026 style)
- Open https://go.dev/tour → finish at least Basics + More types (≈ 2–3 hours)
- Install Go on your laptop (go version should show ≥ 1.23 or 1.24)
- Do the Get Started tutorial
- Come back to Tour and finish Methods & Interfaces + Concurrency
- Build something small:
- CLI todo app
- Simple HTTP server
- File downloader with goroutines
One more realistic example – Goroutine + Channel (Go’s killer feature)
|
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 |
package main import ( "fmt" "time" ) func worker(id int, ch chan string) { time.Sleep(time.Second * 1) ch <- fmt.Sprintf("Worker %d finished!", id) } func main() { ch := make(chan string, 5) // buffered channel for i := 1; i <= 5; i++ { go worker(i, ch) // start 5 workers concurrently! } for i := 1; i <= 5; i++ { msg := <-ch fmt.Println(msg) } fmt.Println("All done! 🚀") } |
Output (order may vary):
|
0 1 2 3 4 5 6 7 8 9 10 11 |
Worker 3 finished! Worker 1 finished! Worker 5 finished! Worker 2 finished! Worker 4 finished! All done! 🚀 |
This is why people fall in love with Go — clean concurrency without too much pain.
So… ready to start? Go to https://go.dev/tour right now and do the first 5 slides — I’ll wait 😄
Any part you want me to explain deeper — slices vs arrays, pointers, interfaces, error handling, or modules? Just ask!
