The birth background and original intention of Go language

The Go language was born at Google to solve the problems of C's complexity and insufficient concurrency support. Its original intention is to create a simple, easy-to-learn, efficient concurrency, memory-safe, cross-platform language to improve programmer productivity, build reliable and scalable systems, and promote code porting and sharing.

The birth background and original intention of Go language

The birth background of Go language

In the early 2000s, Google engineers struggled to develop large-scale distributed systems using C. While C is powerful, it is complex, error-prone, and lacks built-in concurrency support.

In order to solve these problems, Google engineers Robert Griesemer, Rob Pike and Ken Thompson began to explore the design of a new programming language that would have the following characteristics:

• Simple Easy to learn: The syntax is simple and easy to understand, avoiding unnecessary complexity.
• Efficient concurrency: Supports concurrent programming, making it easy to write scalable and high-performance programs.
• Memory safety: Automatically manage memory to prevent common memory errors such as leaks and out-of-bounds access.
• Cross-platform: Can be compiled and run on a variety of operating systems and architectures to ensure code portability.

The original intention of the Go language

The original intention of the Go language is to create a language suitable for the development of large-scale distributed systems at Google. The language aims to:

• Increase programmer productivity: Simplify the development process through a concise syntax and a powerful toolset.
• Build reliable and scalable systems: Provides built-in concurrency support, memory safety, and effective management mechanisms for large code bases.
• Cross-platform support: Allows code to be easily ported and deployed in different environments, promoting team collaboration and code sharing.

Practical case

A simple Go language program showing concurrency features:

package main

import (
    "fmt"
    "time"
)

func main() {
    // 创建一个并发管道
    ch := make(chan int)

    // 启动一个协程发送数据到管道
    go func() {
        for i := 0; i < 10; i++ {
            time.Sleep(time.Second)
            ch <- i
        }
    }()

    // 主协程从管道接收数据
    for {
        data, ok := <-ch
        if !ok {
            break
        }
        fmt.Println(data)
    }
}

In this program, we will create a Pipech is used for data communication between coroutines. A coroutine continuously sends data to the pipe in the background, and the main coroutine receives data from the pipe and prints it. This demonstrates a simple and efficient way of concurrent programming in Go language.
