Revealing the origin of Golang: exploring the origins between Golang and Google

The mystery of Golang’s life experience: Revealing the origins between Golang and Google

Since its inception, the Go language (Golang) has been famous for its simplicity, efficiency and concurrency features. Very popular among programmers. However, little is known about the origins of this programming language. In fact, the origin of the Go language is inextricably linked to Google, a world-renowned technology giant.

The story of the Go language began in 2007, when engineers at Google began to face increasingly complex software engineering challenges, especially in the development and maintenance of large-scale distributed systems. Traditional programming languages ​​were unable to solve these problems, so Google began to look for a new programming language that was more suitable for its needs.

After a period of research and discussion, Google’s engineering team determined a plan to create a new programming language. So, three famous computer scientists, Ken Thompson, Robert Griesemer and Rob Pike, began this journey of exploration. Their goal was to develop a language that was efficient, concise, and capable of supporting concurrent programming to meet Google's growing software engineering needs.

After years of research and development and iteration, the Go language was finally officially released in 2009. As an open source programming language, Go language has quickly won the favor of programmers around the world with its concurrent programming model, garbage collection mechanism and elegant syntax design.

Although the Go language was created by Google engineers, Google did not keep it as the company's proprietary technology, but chose to open source it and share it with the world. This means that anyone can freely use, modify and share the source code of the Go language, bringing a huge impact to the entire development community.

Below we use some specific code examples to reveal the origin between the Go language and Google:

Example 1: Concurrent Programming

package main

import (
    "fmt"
    "time"
)

func main() {
    go printNumbers()
    go printLetters()
    time.Sleep(time.Second * 2)
}

func printNumbers() {
    for i := 1; i <= 5; i++ {
        time.Sleep(time.Millisecond * 500)
        fmt.Printf("%d ", i)
    }
}

func printLetters() {
    for i := 'a'; i <= 'e'; i++ {
        time.Sleep(time.Millisecond * 500)
        fmt.Printf("%c ", i)
    }
}

In this example, we show It has the powerful concurrent programming capabilities of Go language. By using the go keyword, we can create concurrent goroutines to perform different tasks. In this example, the two functions printNumbers() and printLetters() are executed concurrently in different goroutines, printing numbers and letters respectively, and finally passing time.Sleep () to wait for all goroutines to complete execution.

Example 2: Garbage Collection

package main

import (
    "fmt"
    "runtime"
)

func main() {
    var x []int

    for i := 0; i < 1000; i++ {
        x = append(x, i)
    }

    fmt.Println("NumGoroutine:", runtime.NumGoroutine())
}

In this example, we show the excellent garbage collection mechanism of Go language. Through the runtime.NumGoroutine() function, we can get the number of goroutines in the current program to understand the concurrency of the program. The garbage collector of the Go language will automatically handle objects that are no longer used to avoid memory leaks.

Summary
Through the above code examples, we have an in-depth understanding of the powerful features of the Go language as a modern programming language, including concurrent programming and garbage collection. These features are exactly the needs and challenges that Google engineers considered when developing the Go language. After the release of the Go language, it has brought many conveniences to Google and developers around the world.

Although the mystery of the Go language’s origin has been revealed, its continuous innovation and development potential will continue to bring us more surprises and inspirations. I hope we can explore more possibilities in this excellent programming language and jointly promote the development and progress of technology.
