Introduction

About Go

"Go will be the server language of the future." - Tobias Lütke, Shopify

What is Go?

Go (or Golang) is a modern, open-source programming language created by Google engineers Robert Griesemer, Rob Pike, and Ken Thompson. Launched in 2009 and publicly released in 2012, Go bridges the gap between:

  • High-performance statically typed languages (like C++)
  • Developer-friendly dynamic languages (like Python)

Key Features

Simplicity and Readability

Clean and Simple

  • Only 25 keywords in total
  • Easy to learn and read
  • Built-in gofmt tool for consistent formatting
  • Reduces cognitive load on developers

Strong Typing with Inference

Type System

// Explicit typing
var age int = 25

// Type inference
name := "Go"  // Compiler infers string type

Go combines safety with convenience through its smart type system.

Excellent Concurrency Support

Built for Modern Computing

Lightweight threads that make concurrent programming simple: 

1
go function()  // Runs in background

Type-safe communication between goroutines: 

1

3
ch := make(chan string)
ch <- "message"  // Send
msg := <-ch     // Receive

Fast Compilation

Speed Features

  • Smart dependency management
  • Optimized build system
  • Quick compile times even for large projects
  • Enhanced developer productivity

Garbage Collection

Memory Management

  • Automatic memory management
  • Efficient garbage collector
  • No manual memory allocation/deallocation
  • Optimized for performance

Rich Standard Library

Built-in Packages

  • Networking
  • Cryptography
  • HTTP servers
  • JSON/XML processing
  • Testing frameworks
  • And much more!

Cross-Platform Compilation

Build Once, Run Anywhere

# Build for Mac from Linux
GOOS=darwin GOARCH=amd64 go build

Perfect Use Cases

Where Go Shines

Docker and Kubernetes

  • Powers Docker and Kubernetes
  • Excellent for cloud infrastructure
  • Built for scalability
  • Container-friendly design
  • High-performance servers
  • Real-time applications
  • API services
  • Web servers

func main() {
    // Your CLI tool
}
- Dependency-free binaries - Cross-platform support - Fast execution - Easy distribution

  • Quick startup time
  • Low memory footprint
  • Built-in HTTP support
  • Easy deployment

Philosophy

Go Proverb

"Less is exponentially more" - Rob Pike

Design Principles

  • Simplicity over complexity
  • Clarity over cleverness
  • Practicality over theory
  • Performance without obscurity

Go 1.18+ added generics while maintaining these core values!
