Review of Milestone Events Released by Golang

Since its birth, the Go language has been developing rapidly and frequently releases new versions and important events. This article will review some of the milestones released by Golang, combined with specific code examples, to demonstrate the excellent features and innovations of this excellent programming language as it continues to evolve.

The Go language was launched by Google in 2007, and today it has become an efficient and concise programming language favored by programmers. During its development process, new versions and features have been continuously introduced to meet developers' needs for efficient programming.

1. Go 1.0 released

On March 28, 2012, Go 1.0 version was officially released, marking that the Go language has entered a stable stage. The release of Go 1.0 version solves the instability and incompatibility issues of previous versions and provides a solid foundation for subsequent versions.

Code example:

package main

import "fmt"

func main() {
    fmt.Println("Hello, world!")
}

The above is an example of a simple Hello World program, which demonstrates the simplicity and readability of Go language.

2. Introduction of Go Modules

On February 25, 2019, version 1.11 of the Go language introduced the Go Modules mechanism. This feature makes the package management of the Go language simpler and more convenient. Go Modules allow developers to easily manage project dependencies, greatly improving development efficiency.

Code example:

go mod init example.com/hello

The above command is used to initialize a Go Modules project to facilitate developers to manage project dependencies.

3. Go 1.11 HTTP module upgrade

On August 24, 2018, Go language released version 1.11, which made a major update to the native HTTP module. This update provides more efficient HTTP/2 support and optimizes the performance of HTTP services.

Code example:

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello, %s!", r.URL.Path[1:])
}

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

The above example is a simple HTTP service code that demonstrates the excellent concurrency processing capabilities of the Go language.

4. Go version 1.14 improves performance

On February 25, 2020, the Go language released version 1.14, which improved module performance, compilation speed and runtime efficiency. The release of this version further improves the performance of the Go language.

Code example:

package main

import "fmt"

func main() {
    nums := []int{1, 2, 3, 4, 5}
    sum := 0
    for _, num := range nums {
        sum += num
    }
    fmt.Println("Sum:", sum)
}

The above example is a code that calculates the sum of array elements, demonstrating the efficient performance of the Go language.

By reviewing the above milestones released by Golang, we can see the continuous progress and innovation of this programming language in all aspects. I believe that in the future, Go language will continue to be the first choice for developers, bringing us more surprises and conveniences.
