Go – Programming Language

Go (Golang) is an open-source programming language developed by Google. Designed for simplicity and efficiency, Go excels at building reliable, scalable infrastructure and command-line tools.

Key Features

• Fast Compilation: Near-instant build times
• Static Typing: Type safety with inference
• Concurrency: Built-in goroutines and channels
• Single Binary: No runtime dependencies
• Standard Library: Comprehensive built-in packages

Installation

Install Go on Ubuntu:

wget https://go.dev/dl/go1.21.5.linux-amd64.tar.gz
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf go1.21.5.linux-amd64.tar.gz
echo "export PATH=\$PATH:/usr/local/go/bin" >> ~/.bashrc
source ~/.bashrc

Usage Examples

Go programming examples:

package main

import (
    "fmt"
    "net/http"
)

// HTTP server
func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "Hello, World!")
    })
    http.ListenAndServe(":8080", nil)
}

// Goroutine example
func processItems(items []string) {
    for _, item := range items {
        go process(item)
    }
}

Benefits

Go combines simplicity with performance. Its opinionated design eliminates decision fatigue while delivering efficient executables perfect for cloud-native development.
