"Which devices are suitable for running Go language programs? 》, need specific code examples

Go language is an open source programming language developed by Google. It has efficient compilation speed, concise syntax structure and powerful concurrency features, so it is very popular among programmers. So, which devices are suitable for running Go language programs? This article discusses this issue from different device perspectives and provides specific code examples.

1. Personal Computer
   First of all, personal computers are the most common devices for running Go language programs. Whether it is Windows, Mac or Linux system, Go language can run well. The following is an example of a simple Go language program that prints "Hello, World!" to the console:

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

2. Server
   The high concurrency nature of the Go language makes it an ideal Ideal for server-side applications. Whether it is a traditional physical server or a cloud server, it can well support the running of Go language programs. Here is an example of a simple web server built using Go language:

   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)
   }

3. Embedded devices
   In addition to personal computers and servers, Go language can also run on embedded devices, For example, Raspberry Pi, Arduino, etc. Due to the cross-platform features and static compilation capabilities of the Go language, Go programs can be easily compiled into executable files suitable for different architectures. The following is a simple Go language program example for controlling LED lights:

   package main
   
   import (
    "github.com/stianeikeland/go-rpio/v4"
    "time"
   )
   
   func main() {
    if err := rpio.Open(); err != nil {
        fmt.Println(err)
        return
    }
    defer rpio.Close()
   
    pin := rpio.Pin(10)
    pin.Output()
   
    for {
        pin.Toggle()
        time.Sleep(time.Second)
    }
   }

Generally speaking, whether it is a personal computer, server or embedded device, as long as it supports the Go language running environment , you can run Go language programs very well. Through the discussion and specific code examples in this article, I believe readers will have a clearer understanding of which devices are suitable for running Go language programs.
