The language borrowing genealogy of Go language

The Go language borrows from four languages: Algol (modularity and concurrency), C (syntax and type system), Oberon (module system and concurrency model), and Smalltalk (garbage collector and interface mechanism). These borrowed elements contribute to the modern, safe and easy-to-use features of the Go language, as shown in the following practical case: creating an HTTP server that prints the parameters in the request, reflecting the influence of the C language (syntax and type system), Oberon The impact of the language (module system and concurrency model) and the impact of the Smalltalk language (garbage collector).

Go language's language borrowing genealogy

Introduction

Go language by Rob · Designed and developed by Pike, Robert Grisham, and Ken Thompson at Google in 2009. Since then, it has become a popular programming language used to build a variety of applications. The Go language borrows from several other programming languages, including:

• Algol: The Go language is influenced by the Algol family of languages, especially Algol 68, which emphasizes modularity and concurrency. .
• C: The syntax and type system of the Go language are similar to C, but safer and easier to use.
• Oberon: Oberon’s module system and concurrency model had a significant impact on the design of the Go language.
• Smalltalk: The garbage collector and interface mechanism of the Go language are inspired by Smalltalk.

Practical case: Web application

Let us use a practical case to demonstrate the language reference of Go language. We create a simple HTTP server that prints the parameters in the request to the terminal.

package main

import (
    "fmt"
    "log"
    "net/http"
)

func main() {
    // 创建一个 HTTP 处理程序。
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        // 遍历请求的参数。
        for k, v := range r.URL.Query() {
            // 打印键值对。
            fmt.Fprintf(w, "%s: %s\n", k, v)
        }
    })

    //启动 HTTP 服务器。
    log.Fatal(http.ListenAndServe(":8080", nil))
}

In the above code:

• C language influence: The syntax and type system are similar to the C language.
• Oberon language impact: Use of module system and concurrency model.
• Smalltalk language impact: Use of garbage collector.

By combining the features of these different languages, the Go language creates a modern, safe and easy-to-use programming language.
