Comparison of similarities and differences between Go language and Golang

Go language and Golang are the same language, so comparison cannot be made. In fact, "Go" and "Golang" both refer to different names of the Go language, and there is no difference between the two in terms of the language itself. Go language is an open source programming language developed by Google, aiming to improve development efficiency and simplify code design. The following will introduce the features and sample codes of the Go language in detail to help readers better understand this language.

1. Language features

• Concurrency support: Go language has built-in support for lightweight threads (goroutine) and channels (channels), making it easy to write efficient concurrent programs.
• High performance: Go language compiles quickly, supports garbage collection, and has excellent performance.
• Simple and clear: Go language design is simple, easy to read and write, and the code structure is clear.

2. Sample code

Concurrent programming

package main

import (
    "fmt"
    "time"
)

func printNumbers() {
    for i := 0; i < 5; i++ {
        fmt.Println(i)
        time.Sleep(time.Millisecond * 500)
    }
}

func main() {
    go printNumbers()  // 启动goroutine
    time.Sleep(time.Second * 3)
    fmt.Println("Main goroutine 结束")
}

HTTP server

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)
}

The above is a simple Go language HTTP server example, which can be Visit http://localhost:8080 in the browser to view the results.

Conclusion

In general, Go language is a powerful, concise and clear programming language, suitable for building high-performance concurrent applications. Through the demonstration of sample code, readers can understand the characteristics and usage of Go language more intuitively. I hope this article can help readers have a deeper understanding of the Go language.
