Go Programming Handbook

Introduction
Go is a statically typed, compiled programming language designed for building simple, reliable, and efficient software.

Core Concepts
- **Goroutines**: Lightweight threads managed by Go runtime
- **Channels**: Communication mechanism between goroutines
- **Interfaces**: Define behavior without specifying implementation

Best Practices
1. Keep packages focused and small
2. Use meaningful variable names
3. Handle errors explicitly
4. Write tests for all packages

Example: Concurrent HTTP Server
go
package main

import (
"fmt"
"net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello, %s!", r.URL.Path[1:])
}

func main() {
http.HandleFunc("/", handler)
http.ListenAndServe(":8080", nil)
}
