Go Introduction

Description

Go (often referred to as Golang) is an open-source programming language created at Google in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. It is a statically typed, compiled language designed for simplicity, high performance, and reliability. Go is syntactically similar to C but adds memory safety, garbage collection, structural typing, and CSP-style concurrency.

Pros & Cons

✅ Pros

  • High Performance: Compiled directly to machine code.
  • Concurrency Support: Built-in Goroutines and Channels.
  • Simple Syntax: Easy to learn for developers coming from Python, Java, or C++.

❌ Cons

  • No Generics (in older versions): Generics were added in Go 1.18.
  • Implicit Interface Implementation: Can be confusing for beginners.

When to Use

Use Go for building scalable cloud services, microservices, distributed systems, and CLI tools.

Example

This is a minimal 'Hello, World' program in Go.

package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}

Best Practices

Use `gofmt` to automatically format your code. Go developers value consistency.
