Statically typed compiled programming language designed for simplicity and efficiency

Core Idea: Go (or Golang) is a programming language created by Google that combines the efficiency and safety of a statically typed compiled language with the ease of use and developer productivity of modern dynamic languages.

Key Elements

• Language Characteristics

  • Statically typed with type inference
  • Garbage collection for memory management
  • Strong built-in concurrency support via goroutines and channels
  • Explicit error handling (no exceptions)
  • Fast compilation times
  • Single binary output (no dependencies)
  • Cross-platform compatibility
  • Built-in testing framework

• Key Features

  • Goroutines for lightweight concurrent execution
  • Channels for communication between goroutines
  • Interfaces for implicit type composition
  • Defer statement for resource cleanup
  • Reflection capabilities
  • Built-in formatting tools (gofmt)
  • Standard library with extensive functionality
  • Module system for dependency management

• Common Use Cases

  • Backend web services and APIs
  • Command-line applications
  • Network programming
  • System utilities
  • DevOps tools and infrastructure
  • Cloud-native applications
  • Microservices
  • Performance-critical applications

• Code Example

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