Prerequisites  前提条件

  • Some programming experience. The code here is pretty simple, but it helps to know something about functions.  一些编程经验。这里的代码非常简单。但是具备函数的一些知识是有帮助的。
  • A tool to edit your code. Any text editor you have will work fine. Most text editors have good support for Go. The most popular are VSCode (free), GoLand (paid), and Vim (free).  一款编辑代码的工具。任何你可接受的文本编辑器。许多文本编辑器为Go提供了良好的支持。非常受欢迎的有VSCode（免费），GoLand（付费），和Vim（免费）。

Install Go  安装Go

Just use the Download and install steps.

只需参考下载和安装步骤。

Write some code  编写一些代码

Get started with Hello, World.

从Hello, World开始。

cd
cd %HOMEPATH%
mkdir hello
cd hello
$ go mod init example/hello
go: creating new go.mod: module example/hello
package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}
$ go run .
Hello, World!
$ go help

Call code in an external package  调用外部包的代码

When you need your code to do something that might have been implemented by someone else, you can look for a package that has functions you can use in your code.

当你需要你的代码做一些工作（这些工作可能已有其他人实现），你可以查找实现了功能（可以在你的代码中使用的功能）的包。

package main

import "fmt"

import "rsc.io/quote"

func main() {
    fmt.Println(quote.Go())
}
$ go mod tidy
go: finding module for package rsc.io/quote
go: found rsc.io/quote in rsc.io/quote v1.5.2
$ go run .
Don't communicate by sharing memory, share memory by communicating.
