How do I complete a tour of go?

# Interactive Go Basics Visit [go.dev/tour](https://go.dev/tour/welcome/1). 81 - **Sections:** Basics (variables, functions), Flow Control (if, switch, defer), More Types (structs, slices, maps), Methods & Interfaces, Generics, Concurrency (goroutines, channels). - Interactive: Edit/run code in browser (Shift+Enter). - Progress through all modules, complete exercises. Practice reinforces syntax hands-on.

How do I practice with go by example?

# Hands-On Examples Go to [gobyexample.com](https://gobyexample.com/). 82 - Run all 50+ examples: Hello World to HTTP Servers. - Copy-paste into local files, run `go run example.go`. - Key topics: Slices, Maps, Goroutines, Channels, JSON, Testing. ```go // Example: Goroutines go func() { fmt.Println("Hello") }() ``` Clone locally for offline practice.

How do I learn idiomatic go & modules?

# Write Real Code 1. Read [Effective Go](https://go.dev/doc/effective_go). 83 - Key: `gofmt`, naming (MixedCaps), defer for cleanup, multiple returns, interfaces. 2. Create module [per go.dev/doc/code](https://go.dev/doc/code): 79 ```bash go mod init example.com/user/cli # Add hello.go, main.go go build go test # Add _test.go ``` 3. Run `go fmt ./...`; study examples.

How do I build a cli project?

# Apply Skills: CLI Tool 1. Project: Simple URL shortener or TODO CLI. ```bash mkdir todo-cli cd todo-cli go mod init todo-cli go get github.com/spf13/cobra@latest # For CLI flags ``` 2. Structure: - `cmd/todo/main.go`: CLI entry. - `internal/todo/todo.go`: Logic. - `todo_test.go`: Tests. 3. Implement add/list (use slices/maps), build `go install`, test. 4. Extend with concurrency if ready. Real-world project solidifies learning.

Q: How do I set up go environment?

# Install Go 1. Download the latest Go from [go.dev/dl](https://go.dev/dl/) (current: Go 1.26.0 or later). 78 77 **Linux/macOS:** ```bash wget https://go.dev/dl/go1.26.0.linux-amd64.tar.gz # Adjust version/OS sudo tar -C /usr/local -xzf go1.26.0.linux-amd64.tar.gz mkdir -p ~/go/{bin,src,pkg} export PATH=$PATH:/usr/local/go/bin ``` Add to `~/.bashrc` or `~/.zshrc`. **Windows:** Run MSI installer, verify PATH. 2. Verify: `go version` 3. Hello World: ```bash mkdir hello cd hello go mod init hello go.mod created echo 'package main import "fmt" func main() { fmt.Println("Hello, Go!") }' > hello.go go run . ``` This builds a strong foundation for coding.

Install Go

Download the latest Go from go.dev/dl (current: Go 1.26.0 or later).Linux/macOS:

wget https://go.dev/dl/go1.26.0.linux-amd64.tar.gz  # Adjust version/OS
sudo tar -C /usr/local -xzf go1.26.0.linux-amd64.tar.gz
mkdir -p ~/go/{bin,src,pkg}
export PATH=$PATH:/usr/local/go/bin

Add to ~/.bashrc or ~/.zshrc.

Windows: Run MSI installer, verify PATH.

Verify: go version
Hello World:

mkdir hello
cd hello
go mod init hello
go.mod created
echo 'package main
import "fmt"
func main() { fmt.Println("Hello, Go!") }' > hello.go
go run .

This builds a strong foundation for coding.

Why this step matters:

-Establishes your development workspace reliably
-Enables running real Go code immediately

30-60 minutes

Terminal/Command Prompt, Text editor (VS Code), Web browser

$0

Definition of Done

•`go version` shows installed version
•Hello world program runs with `go run .`

Common Mistakes to Avoid

❌ PATH not updated correctly

→Restart terminal or source ~/.bashrc; check `echo $PATH`

❌ Wrong architecture download

→Select correct OS/CPU from go.dev/dl/
