go Online Compiler

package main

import (
    "fmt"
    "time"
)

func main() {
    fmt.Println("Hello, World!")
    fmt.Println("Welcome to Go Online Compiler")
    
    // Variables
    language := "Go"
    version := 1.21
    isCompiled := true
    
    fmt.Printf("Language: %s\n", language)
    fmt.Printf("Version: %.1f\n", version)
    fmt.Printf("Is compiled: %t\n", isCompiled)
    
    // Slices and maps
    numbers := []int{1, 2, 3, 4, 5}
    fmt.Println("Numbers:", numbers)
    
    // Goroutines simulation
    ch := make(chan string, 3)
    
    go func() {
        ch <- "Hello from goroutine 1"
    }()
    
    go func() {
        ch <- "Hello from goroutine 2"  
    }()
    
    go func() {
        ch <- "Hello from goroutine 3"
        close(ch)
    }()
    
    // Read from channel
    for msg := range ch {
        fmt.Println(msg)
    }
    
    // Structs and methods
    p := Person{Name: "Developer", Age: 30}
    p.Greet()
}

type Person struct {
    Name string
    Age  int
}

func (p Person) Greet() {
    fmt.Printf("Hi, I'm %s and I'm %d years old.\n", p.Name, p.Age)

About Go Programming

Go (Golang) is an open-source programming language developed by Google. It's designed for simplicity, efficiency, and excellent support for concurrent programming through goroutines and channels.

Go combines the performance of compiled languages with the ease of use of interpreted languages. It's particularly popular for building web servers, microservices, and cloud-native applications.

Use our Go online compiler to learn concurrent programming concepts, build network applications, or explore Go's clean syntax and powerful standard library.
